Unable to perform assignment because the size of the left side is

I am trying to pull rows from different matrices and add them to one matrix but I am not sure of the syntax to do this correctly.

What I have at the moment is as follows...

data1(1,:) = PAR1rs(1,:)

data1(2,:) = PAR3rs(1,:)

data1(3,:) = PAR4rs(1,:)

data1(4,:) = PAR5rs(1,:)

data1(5,:) = PAR6rs(1,:)

But it returns the following error...

Unable to perform assignment because the size of the left side is 1-by-61492 and

the size of the right side is 1-by-60522.

The error is clearly saying that the size matrices do not match. data1 must be a 5x60522 matrix.

How do I write the code to create a matrix that accepts different row lengths?

[Abdolkarim Mohammadi]

MATLAB cannot handle jagged arrays. You should use cell arrays instead. For example:

data1 = cell (5, 1);
data1{1} = PAR1rs(1,:);
.
.
.

Thank you.
