If n is a scalar, then each element of v is repeated n times. The length of u is length(v)*n. If n is a vector, then it must be the same length as v. Each element of n specifies the number of times to repeat the corresponding element of v.

An empty string contains zero characters. When you display an empty string, the result is a pair of double quotes with nothing between them (""). The missing string is the string equivalent to NaN for numeric arrays. It indicates where a string array has missing values. When you display a missing string, the result is <missing>, with no ...end executes a group of statements in a loop for a specified number of times. values has one of the following forms: initVal:endVal — Increment the index variable from initVal to endVal by 1, and repeat execution of statements until index is greater than endVal. initVal:step:endVal — Increment index by the value step on each iteration, or ...1.b. I have also a text file somewhere in which there is a particular symbol "[$1]" (excluding the quotation marks), I would like to replace [$1] with the resulting string in 1.a. ( If I use a loop as above to generate the string, it is easy, but I want to be able to do this operation without a loop)The repetition operator is denoted by a '*' symbol and is useful for repeating strings to a certain length. Example: str = 'Python program' print(str*3) The above lines of code will display the following outputs: Python programPython programPython program. Similarly, it is also possible to repeat any part of the string by slicing: Example:Neanderthals, new evidence shows, made fiber cordage — a skill we have never before attributed to them. Advertisement Have you ever tried to make string? It's actually a bit tricky...Count the number of occurrences of the string, red, in string arrays. You can create a string using double quotes. str = "paired with red shoes". str =. "paired with red shoes". To count the occurrences of red, use the count function. In this example, the result is 2 because red is also part of the word paired.

A = rand(3,3) A =. 0.4170 0.3023 0.1863. 0.7203 0.1468 0.3456.Categorical Arrays. categorical is a data type to store data with values from a finite set of discrete categories. For example, the syntax C. = categorical({'R','G','B','B','G','B'}) creates a categorical array with six elements that belong to the categories R , G, or B. A categorical array provides efficient storage and convenient manipulation ...If A and B are both ordinal categorical arrays, they must have the same sets of categories, including their order. If neither A nor B are ordinal, they need not have the same sets of categories, and the comparison is performed using the category names. In this case, the categories of C consist of the categories of A followed by the categories of B that are not in A.How to manually space XticksIf n is a scalar, then each element of v is repeated n times. The length of u is length(v)*n . · If n is a vector, then it must be the same length as v . Each ...

B = arrayfun(___,Name,Value) applies func with additional options specified by one or more Name,Value pair arguments. For example, to return output values in a cell array, specify 'UniformOutput',false.You can return B as a cell array when func returns values that cannot be concatenated into an array.

Your problems are probably caused by the way MATLAB handles strings. MATLAB strings are just arrays of characters. When you call ['cow','dog','cat'], you are forming 'cowdogcat' because [] concatenates arrays without any nesting. If you want nesting behaviour you can use cell arrays which are built using {}.

Say I have a column vector x=[a;b;c]. I want to repeat each element n times to make a long length(x)*n vector. For example, for n=3, the answer would be: ans= a a a b b b ... Description. case case_expression, end evaluates an expression and chooses to execute one of several groups of statements. Each choice is a case. The switch block tests each case until one of the case expressions is true. A case is true when: For numbers, case_expression == switch_expression. == 1. The numel () function is used to return the number of elements present in a specified array. Syntax: numel (A) Example: Matlab. % MATLAB code for detection of duplicate. % values of the array using numel() % Initializing an array. A = [0 2 4 1 2 3 0 4] % Calling the unique() function.DateString = datestr(t) converts the datetime values in the input array t to text representing dates and times. The datestr function returns a character array with m rows, where m is the total number of datetime values in t. By default, datestr returns text in the format, day-month-year hour:minute:second.example. M = mode(A) returns the sample mode of A, which is the most frequently occurring value in A. When there are multiple values occurring equally frequently, mode returns the smallest of those values. For complex inputs, the smallest value is the first value in a sorted list. If A is a vector, then mode(A) returns the most frequent value of A.Character arrays and string arrays provide storage for text data in MATLAB ®. A character array is a sequence of characters, just as a numeric array is a sequence of numbers. A typical use is to store short pieces of text as character vectors, such as c = 'Hello. World'. A string array is a container for pieces of text.finding duplicates. Learn more about unique . unique(A)=[1 2 3]; but I want to find the duplicates that are not the first occurrence. i.e x=[2 4 6 7]; I typed help unique but I couldn't figure out if I and J reported by this function helps with my purpose.I know that I can program it but i want to be as efficient as possible in my codes to reduce the running time.Description. u = repelem(v,n) , where v is a scalar or vector, returns a vector of repeated elements of v. If n is a scalar, then each element of v is repeated n times. The length of u is length(v)*n. If n is a vector, then it must be the same length as v. Each element of n specifies the number of times to repeat the corresponding element of v.DateString = datestr(t) converts the datetime values in the input array t to text representing dates and times. The datestr function returns a character array with m rows, where m is the total number of datetime values in t. By default, datestr returns text in the format, day-month-year hour:minute:second.You also can call cellfun on a string array. For compatibility, cellfun treats each element of a string array as though it were a character vector. If you specify a function that returns text, then cellfun returns it as a cell array of character vectors, not as a string array. Create abbreviations for names in a string array using cellfun.All you needed is a string concatenation which, in MATLAB, is similar to declaring a matrix e.g. a = ['my' 'name' 'is' 'Bolshoi'] Share. Improve this answer ... Note that you'll have to use num2str to combine the integer value of the loop counter and the string value of the variable. However, carefully consider using this approach.
