With "Matrices and Curves Fitting Calculator mobile" application, you can compute matrices (addition, subtraction, multiplication), solve linear systems and approximate any series of data values with different curves fitting plotted on the iPhone screen (Linear, Hyperbolic, Logarithmic and Power regression), all these features come in a well designed professional user interface optimized for the iPhone and iPod Touch.
"Matrices and Curves Fitting Calculator mobile" application integrates its own customized and well designed permanent keyboard to make it even easier to enter your data to the application.

"Matrices and Curves Fitting Calculator mobile" integrates all the following features:

Matrices
- Flexible matrix size starting from 1x1 and up to 8x8
- Transpose input and result matrices
- Copy a matrix to another matrix (For instance you can use this feature to compute A*A, copy the results into one of he matrices input ...)
- Matrices addition: A+B
- Matrices subtraction: A-B
- Matrices multiplication: A*B
- Solving linear system: A.X=B

Curves fitting:
Enter up to 100 data points for curve fitting calculation using the method of Least Squares method. The supported curves fittings are:
- Linear regression: y=a*x+b
- Hyperbolic regression: y=x/(a*x+b)
- Logarithmic regression: y=a*ln(x)+b
- Power regression: y=a*x^b

The application also:
- Plots on the screen the computed curves and all entered data points
- Adapts dynamically the X and Y axis each time a new data point is entered

This application is very useful for students, engineers, professors and researchers.
