Traffic Count vs Matrix Wise Matrix Calculator

Track traffic effortlessly with this powerful traffic count app for iOS. Count cars, trucks, bicycles, and pedestrians across multiple times and locations. Export your data and import it on other devices for seamless data management.

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.
