I have an anonymous function defined in a string. Although, I would like to use this string to define a function handle, so as the string contents is used to define a new variable. For example: I have A = '[x(1)^2+x(2)+x(3),-x(5)+x(3);0,x(1)^3]'; And I would like to have f = @(x) [x(1)^2+x(2)+x(3),-x(5)+x(3);0,x(1)^3]; In such a way that f([1 1 1 1 1]) = [3 0;0 1]; Do you know any function of matlab that I could use to convert this string in a way that the variable A can be used to define the function handle?
