Description:

The full version of  TouchSheet programm (for touchscreen mobile phones) is a revolutionary mathematical tool for mobile phones. The program is  must-have for students, engineers and researchers. TouchSheet program includes four (04) applications (Statistics, Curve fitting, Interpolation and Matrix operations) with a large of features. The famous TouchSheet is designed in order to fullfill the needs of every one(student, engineer, researcher... .). By using the revolutionary programs made by mobile-sciences you can make your handset as home computer and will get substantially all of the computing capabilities desired by a large fraction of the public.

Released version (TouchSheet V3.0):

Applications's description:

1. Statistics

Menu definition GAU : Gaussian LOG : Logistic LOR: Lorentzian Back: back to main menu

2. Curve fitting(Regression):

Curve fitting program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, and nonlinear functions. The regression analysis determines the values of the parameters that cause the function to best fit the observed data that you provide.

• Polynomial fitting
• Multi linear regression
• Non linear regression

Menu definition SLF: Stright line fitting MLF: Multilinear fitting PF: Ploynomial fitting NLF: Nonelinear fitting P: Proceed Back: back to main menu

3. Interpolation using cubic spline.

Menu definition Interpolate at: Interpolate at value of x to be given Back: back to main menu

4. Matrix operations:

Menu definition A : Input of square matrix A B : Input of matrix or vector B A+B: Addition of matrix A to B A-B: Matrix Subtraction A*B: Matirx Multiplication 1/A: Inverse of matrix A |A|: determinant of matrix A B/A: solution of the equation Ax=b Back: back to main menu
