hi, how to store two different matrices as an output parameter of a 'function'.

for example: function[matrix1, matrix2]= input(in1,in2) so matrix1 and matrix2 contain some m*n matrix which i obtain through my logic. how do i put these 2 matrices in my function output ? becoz when i use the above function format, output displays only 1 matrix, ie, in this case matrix1 alone.

thank you.

在 MATLAB Online 中打开

When you invoke the function, you need to provide two variables on output:

[m1, m2] = input(in1, in2);

Note: naming a routine "input" will almost certainly lead to later problems, as "input" is the name of a MATLAB routine.

EDIT: complete example:

>> type rakeshtest
function [matrix1,matrix2] = rakeshtest(in1, in2);
  matrix1 = ones(size(in1));
  matrix2 = zeros(size(in2));
end
>> [m1,m2] = rakeshtest(rand(3,5),rand(2,4))
m1 =
     1     1     1     1     1
     1     1     1     1     1
     1     1     1     1     1
m2 =
     0     0     0     0
     0     0     0     0
