This free scientific calculator can be used to evaluate numeric and also matrix expressions containing real, imaginary or, in general, complex numbers in any form such as
(1/2 + 2i )(3 + 4i) + 3∠(π/4) + sin(i)cos(2 + 3i)^(4 - 2i)
which can also be used for matrix entries.
Swipe number pad to display trigonometric, hyperbolic & other functions.
You can use all standard mathematical functions & operations:
• Addition, subtraction, multiplication, division, exponentiation, 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 it's unique and intuitive user interface, this scientific/complex number calculator computes scientific/mathematical expressions containing complex numbers in standard (rectangular) a+bi and polar (phasor) r∠(θ) forms and optionally converts the result or any complex number in standard form to polar and other modular forms and vice versa
(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.
Do statistics with one or two dimensional real 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 full built-in instructions.

Complex Number & Matrix Calc version 1.6.3.3
Updated At: 2021-05-03
Changes: Redundant app permissions (full network access, view network connections) removed (but still used by Google to show ads).
From previous version:
Some tweaks: text/color, vibration
if crashed on update, uninstall and install again or just delete app data.
Complex Number & Matrix Calc version 1.5
Updated At: 2020-06-09
Changes: The keypad now slides out when scrolling the input window in portrait orientation to enable you see more expressions to more easily select/deselect them. Touching any expression box brings the keypad back into view. You can change this default behavior: Goto Toolbar/Menu and un-check "Full Screen Scrolling".
Improved representation of some calculated values.
There was a mistake in the link to the ads-free (upgrade) version which is now corrected.
Complex Number & Matrix Calc version 1.4
Updated At: 2020-06-01
Changes: Crash fix.
You can now calculate some quantities used in electrical engineering involving complex numbers, i.e., impedance, by selecting expressions (check-boxes are newly added for expression boxes) and long pressing Σ.
You do NOT need internet connection to use this app.

Complex Number & Matrix Calc version 1.3.7.3
Updated At: 2020-03-31
Changes: Bugs fix/performance improvement.
Now non-advanced users can optionally switch to Elementary Complex Calculator for basic operations and automatic conversion between rectangular and polar forms by entering the real and imaginary parts or length and angle separately (rectangular was misspelled as 'rectangulr'!).
Complex Number & Matrix Calc version 1.3.7.2
Updated At: 2020-02-26
Changes: Bug fixes.
The calculator should now be working regardless of your device's language setting.
Use the dot for the decimal symbol when typing a number. The calculator displays the result of a calculation using the dot for the decimal symbol and the comma for the thousands-separator regardless of the language setting. This now enables you to use the features of the calculator (STO, RCL, Ans, Cnvt) in any language setting.
if crashed on update, uninstall app and install again.
