Dear,
I have a program but When I run it, an error occurs:
Error using horzcat
Dimensions of arrays being concatenated are not consistent.
Error in (line 34)
H1_modified = [H1 extra_cols];
How can I fix this error please ?

@Dyuman Joshi We can't specify the final size of H1_modified because the size depends on the code rate. For example H1 is always square, and it depends on the value of m. Then, we add columns to this square matrix H1 in order to get the final matrix H1_modified which must be regular with the desired code rate.

"We can't specify the final size of H1_modified because the size depends on the code rate."
Then what is the relation of final size of H1 with code rate?

On line 34 H1 has m*(m-1) rows, but extra_cols only has m rows. So you can not horizontally concatenate H1 and extra_cols using
H1_modified = [H1 extra_cols];
