Frequently Asked Questions
2×2 and 3×3 matrices are supported for all operations.
Matrix multiplication combines rows of one matrix with columns of the other using dot products, while addition/subtraction simply combines corresponding entries.
The determinant indicates whether a matrix is invertible (a determinant of zero means it isn't) and is used in solving systems of linear equations and calculating area/volume transformations.
Transposing a matrix flips it over its diagonal, turning rows into columns and columns into rows.
Yes — matrix operations come up in computer graphics, data science, and engineering calculations, not just coursework.
