16 Δεκ 2016 · Here are two ways, depending on if you want the extracted "1" to be a character (string) or a number: str = 'M1' % First define the string. str1 = str(2) % Gives a character
Syntax. C = A - B. C = minus(A,B) Description. C = A - B subtracts array B from array A by subtracting corresponding elements. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other.

17 Οκτ 2018 · When reading about numerical methods, then subtraction cancellation is often a topic. Simple example of cancellation: a = 1; b = 1e-16; a-(a+b) = 0. hence we loss all information of b. However, i rarely read about how to check for this problem.
newStr = extract(str,pat) returns any substrings in str that match the pattern specified by pat. If str is a string array or a cell array of character vectors, then the function extracts substrings from each element of str. If pat is an array, then the function matches against multiple patterns. example. newStr = extract(str,pos) returns the ...
