Matricial dot product
Every .dat file contains, separated by " " and "\n", rows and columns of a matrix -BUT in the first line contains always two values containing the dimensions (number of rows, number of columns)
$ sh run.sh will generate 2 sample multiplicable matrices using numpy, and then save them in "A.dat" and "B.dat". The default value of dimension is A(5x20) and B(20x5). Then the script compiles dot.cpp into binary file dot, and finally, ./dot "A.dat" "B.dat" multiply A and B matrices, and save the result in Result.dat.
sh input.sh will read 2 matrix from user interactive input, and then save it in the same "A.dat" and "B.dat" files and multiply them in the same way.
