What function is used to define the input matrix B which is of size 14x2? The size of matrix A is 14x14. If I give it as B=zeros(size(A,1),2), I get a blank line at zero. Why is this so?
The result of B shows two columns of zeros using the above function. But I need some value for the B matrix. I'm bit confused about this.
Please do help me.

zeros(m,n) creates a zero value matrix. That is why you are getting all zero matrixes.
If you want values in B matrix, you can use
  • ones : which puts 1 in all the element
  • (or) rand : which fill your matrix with random number valued between 0 and 1
