Matrix Calculator Pro is a small application useful when learning matrices, which are an important topic of linear algebra. The program turns out to be extremely useful when performing both simple and more complex actions on square matrices. His tasks include determining the sum, difference, product and quotient of two matrices, minimal / maximal elements, as well as transposed, inverse matrices, padding, determinants, orders, etc. The program is very simple and is limited to giving individual elements of the matrix. The results of the work can be saved in the form of a txt and rtf file.
