Matlab repeat string. Things To Know About Matlab repeat string.

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.k = strfind(str,pat) searches str for occurrences of pat. The output, k, indicates the starting index of each occurrence of pat in str. If pat is not found, then strfind returns an empty array, []. The strfind function executes a case-sensitive search. If str is a character vector or a string scalar, then strfind returns a vector of type double.To build block arrays by forming the tensor product of the input with an array of ones, use kron.For example, to stack the row vector A = 1:3 four times vertically, you can use B = kron(A,ones(4,1)).. To create block arrays and perform a binary operation in a single pass, use bsxfun.In some cases, bsxfun provides a simpler and more memory efficient solution.1.b.
