matrix ifft tranform

hi!

i am new to matlab so the solution to my problem will bw easy for you.

i have a matrix with size (12,4), and i want to create a new matrix withe the same size with the ifft result of its row.

my matrix is

     1     1    -1     1
     1     1     1     1
    -1    -1    -1     1

m = [1 1 -1 1   % data matrix
    1 1 1 1
    -1 -1 -1 1
    1 -1 -1 -1
    1 -1 -1 -1
    -1 -1 1 1
    1 1 1 -1
    1 1 1 1
    -1 1 1 -1
    -1 -1 1 1
    -1 1 -1 1
    1 1 1 1];

M = ifft(m, [], 2)   % transform each row
