DescriptionIf A is a vector, then max (A) returns the maximum of A.If A is a matrix, then max (A) is a row vector containing the maximum value of each column of A.If A is a multidimensional array, then max (A) operates along the first dimension of A whose size does not equal 1, treating the elements as vectors. Calculate with arrays that have more rows than fit in memory. However, when the input is a character array, double You can check if your cell is a cell string: This displays the indices and contents of the non-strings: Another idea is, that some strings are multi-row CHAR matrices: You can also explicitelly define the index matrix: idx = strcmp(cellArray, stringToSearchFor); It is kind of verbose, if you review the code in 2 years time, you will still know what is going on. Find elements in table without looping (Matlab). Find the index of each letter. If str is a character vector However, when the input is a character array, double instead converts each character to a number representing its Unicode value. For example, if x0 is a 5-by-3 array, then fmincon passes x to fun as a 5-by-3 array To directly find the elements in X that satisfy the condition X<5, use X(X<5).Avoid function calls like X(find(X<5)), which unnecessarily use find on a logical char | cellstr | strlength | isstring | strings | isstrprop | compose | sprintf. If str is a cell array of character a numeric type will produce an array of the corresponding Unicode code values. String arrays also can contain missing values.
