Run every element through a function and return a new array

Hi, I have a 1000x1 table and I want to run every row through a function y=a*x+b-1 where a and be are constants, and x are the elements from the table. The result should be a new 1000x1 table. Can anybody help?

Cheers.

doc rowfun

using

func = @(x) a*x + b - 1;

should work for this provided a and b are already defined at the point you include the definition of func.

a = 3;
b = 4;
T_out = rowfun(@(x)a*x+b-1,T,'OutputV','data');
