Matlab repeat string.

Mar 22, 2012 · 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 {}. Selected part of the text, returned as a string array, a character vector, or a cell array of character vectors. token includes all text starting at the first character that is not a delimiter and ending at, but not including, the next delimiter. str and token are the same data type. Data Types: string | char | cell.Input array, specified as a vector, matrix, or multidimensional array. If A is a scalar, then sort(A) returns A. If A is complex, then by default, sort sorts the elements by magnitude. If more than one element has equal magnitude, then the elements are sorted by phase angle on the interval (−π, π]. If A is a cell array of character vectors ...This MATLAB function returns the starting index of each substring of str that matches the character patterns specified by the regular expression. ... , then so is the output.

Basically, I am collecting a database of strings and if I run across a duplicate, increase the frequency of that string rather than adding it to ...It would be better to have your 2D pages in the first two dimensions. I.e., B(:,:,j) instead of B(j,:,:). That way the 2D slices are contiguous in memory, and there are many functions in MATLAB and the FEX file exchange that naturally work with "stacked" 3D arrays where the 2D slice is the first two dimensions. E.g., pagemtimes( ).Split, Join, and Sort String Array. MATLAB provides a rich set of functions to work with string arrays. For example, you can use the split, join, and sort functions to rearrange the string array names so that the names are in alphabetical order by last name.. Split names on the space characters. Splitting changes names from a 5-by-1 string array to a 5-by-2 array.Create a string with the same characters, using double quotes. Though it stores 11 characters, str is a 1-by-1 string array, or string scalar.
