I need to write a script that will open a file, read in an integer n, then a matrix of size n x n, then a vector of size n x 1. So for n = 2, there might be a data file (say 'dat.dat1') with first line 2, then 2 lines each with 2 integers, then 2 lines each with 1 integer. But the program needs to work for different positive integers n.
This is what I've tried so far:
fid = fopen('dat.dat1');
n = fgetl(fid);
A = fgetl(fid);
for ii = 1:n-1
A = [A; sscanf(fgetl(fid),'%f')'];
end
b = fgetl(fid);
for jj = 1:n-1
b = [b; sscanf(fgetl(fid),'%f')'];
end
fclose(fid);
But this doesn't seem to work. When I try it out I get an error that says: "Error using vertcat. Dimensions of matrices being concatenated are not consistent."
Any ideas? Also, how could I refactor my code to take the filename as a parameter?
Thanks.
