Easily perform and explore matrix operations on your iPhone or iPad. Work with 1, 2, or 3 matrices, each with custom dimensions up to 4×8, using an intuitive UI designed for clarity and speed. 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. Key Features: • Select 1, 2, or 3 matrices, each up to 4×8 in size • Customize row and column count for each matrix • Choose operations: ◦ Addition (+) ◦ Subtraction (−) ◦ Hadamard product (*) ◦ Element-wise division (/) ◦ Matrix multiplication (@) • Scalar and matrix operations (e.g. multiply a matrix with a scalar) • Echelon form, row-echelon form, reduced row-echelon form transformation • QR factoring (QR decomposition) • LU decomposition with or without pivoting, Crout's algorithm without pivoting • Tap to edit any matrix cell using a built-in keyboard • Keyboard positioning: no keyboard, left, center, right • Keyboard modes: numbers, letters, symbols, functions • Supports math expressions like `1 + 2/3`, `sqrt(2)`, `pow(2, 3)` • Matrix initialization buttons: ◦ AC – All zeroes ◦ ONE – All ones ◦ RND – Random values ◦ SEQ – Sequential values ◦ EYE – Identity matrix ◦ AAC – Set all matrices to zero • Special keys: ◦ BS – Backspace ◦ CLR – Clear selected element ◦ PST – Paste the computed result into a matrix • One-tap actions for: ◦ Transpose (T) ◦ Determinant (Det) ◦ Inverse (Inv) • Expression parser supports basic math and functions: ◦ sqrt, pow, log, exp, sin, cos, tan, and more Designed to make matrix math approachable and efficient, with support for both numeric input and expressions. Note For 3-matrix computation, the multiplication and division operators take precedence over addition and subtraction. You can enter fractions as input (e.g., 1 + 1/2), but the output is always displayed in decimal form.
