Implementation of Strassen Multiplication including zero-padding, parallel programming(multi-thread, openmp respectively)

Implementation of Strassen Algorithm w/ parallel programming for Matrix Multiplication

• I implemented strassen algorithm for matrix multiplication
• I studied parallel parallel programming(very slightly) and implemented multi thread and OpenMP to boost the speed

Performance

• Before the implementation of algorithm, I checked which data structure is the fastest static/dynamic array and vector You can check the code in Performance.cpp

I will keep updating this file...
