You could make use of the results to get hints about zero crossings . Then use fzero to find x value that will give y=0. Sign in to answer this question. For instance, x = -3.55:0.1:3.55; y = x.^2 - 4; Obviously, when x=2 or -2, y=0. But I want to know how to use matlab to find zeros of a function y = f (x) when x is a matrix defined by the user...
In previous versions of MATLAB (before R2016b), you can use the “strfind” function. However, “strfind” returns a cell array of indices. For any input cell whose text does not contain 'bla', “strfind” returns an empty cell. Use “isempty” and “cellfun” with the “find” function to find the empty cells.Description. C = A.^B raises each element of A to the corresponding powers in B. The sizes of A and B must be the same or be compatible.
