Hi ,(adsbygoogle = window.adsbygoogle || []).push({});

I want to compute a geomtric series with matrices. I have the following functions:

add (matrix1,matix2)=function to add 2 matrices.

mult(matirx1,matrix2)=function to multiply two matrices.

I want to create this function in C that computes the following.

I(indentity matrix)

I+A+A^2+A^3+....A^k

I tried

sum=I;

for(i=0;i<k;i++)

{

intermediary=mult(I,A);

sum+=intermediary;

intermediary=mult(intermediary,A)

}

Am I right?

Please, What is wrong here?

Thank you for yout help
