Description
Select the number of matrices, choose an operation from the picker, and input values using a built-in keyboard that supports numbers, letters, symbols, and functions. You can also enter full expressions like `1 + 1/2`, `pow(2, 3)`, or `sqrt(2)` directly into any matrix cell.
Need to fill a matrix quickly? Use dedicated buttons to initialize with zeroes, ones, random values, sequences, or the identity matrix. Perform essential tasks like transpose, determinant, and inverse with just a tap.
Whether you're a student, educator, or engineer, this app provides a powerful and flexible matrix interface right at your fingertips.
