MATLAB: Hi, I have a matrix ,say A=[1 0 0;0 1 0; 1 0 0] ; I Want to change the value of the first column where I have ‘1’ with 01 & 10 respectively. Is it possible? TIA

Question

 A=[1 0 0;0 1 0; 1 0 0] ;

I Want to change the value of the first column where I have '1' with 01 & 10 respectively. Is it possible?

Answer 1

replacements = {[1 0], [0 1]};    %or {'10', '01'}
result = replacements(1+A);

This will give a cell array of values. A cell array is required if you need to preserve the leading '0' of '01': if you were to use

   replacements = [10 01];

then

    >> replacements(1+A)
  ans =
       1    10    10
      10     1    10
       1    10    10
