Complex Number Calculator

Free complex number and matrix calculator, a fully functional scientific calculator for performing calculations on real, imaginary and, in general, complex numbers and matrix expressions. Also for solving systems of linear equations by performing Gauss-Jordan eliminations on augmented matrices containing complex number entries.

You can use all standard mathematical functions & operations, and many more:

• Addition, subtraction, multiplication, division, parallel summation
• Power, exponential & logarithmic functions
• Trigonometric functions and their Inverses
• Hyperbolic functions and their Inverses
• Gamma function, Γ
• Psi function, Ψ
• Zeta function, ζ

Matrices & linear Systems
• Perform matrix algebra.
• Accepts any size matrix
• Determinant, inverse, rank, adjugate, reduced row echelon form, triangular forms
• Augmented matrix
• Solve linear systems
• Shows work.

With its unique and intuitive user interface, this scientific/complex number calculator computes mathematical expressions containing complex numbers in standard (rectangular) a+bi and polar (phasor) r∠(θ) forms and optionally converts the results to rectangular (standard), polar and other modular forms.

(long press i or ∠ to see all forms of the calculated result).

Scientific/Complex number calculations can be performed in RAD (radians) or DEG (degrees) mode.

The results can be displayed with fixed, scientific and engineering notations.

Other Features

• You can also enter functions f(x) or parametric equations p(t) and generate table of values.

Perform statistical analysis on one or two-dimensional real-valued data (you can also use expressions of complex numbers for data as long as they evaluate to real numbers):
• x1, x2, …
• x1, y1; x2, y2; …
Press Σ to do the calculations.

• Calculate combinations C(n, r) and permutations P(n, r).

• Scientific constants.
• Unit converter (Mass, Length, Velocity, ...)

This scientific calculator / complex number calculator / complex matrix calculator contains comprehensive built-in instructions.
