## Description

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.
