I am having problems figuring out how to run simple matrix operations in a program. I am trying to write a encoder using an encoding matrix and can't figure out how to ask the computer to handle the matrices. Please help!

int matrix[10][10];
What else?
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
I have to be able to find the inverse of a matrix and also multiply matrices together. It is a long and complicated process if you do it by hand and I want a computer program which will do it. The idea will be applied to cyrptography and communications.
Use your normal formulas. Where exactly are you having problems? What have you tried?
Also, beware, unless your matrices are of a special type, finding dterminants is a positively hideous problem for large enough matrices.
The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.
Where is your work? Post what you have done and describe the specific problems you are having with it.
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
