SCalc

With more than 100 built-in functions, forms to enter matrix and list data, Scalc calculates matrix inversions, LU (QR) decompositions, definite integrals, derivatives and zeros of simple functions. Solve a system of linear equations using QRS operation. Draw 15 graphs/plots, compute 10 commands. Switch to increasingly complex layouts, solve equations and compute special functions.
Draw parametric, cartesian and polar graphs. Zoom in and zoom out. Track graph functions. Stretch and compact graphs along the y-axis. Compute commands like integrations, derivatives, maxima and minima along with drawings of results on the graphics screen. Also obtain samples of x-y data of graphs or functions. Using x-y data, curve-fit and plot. Use 3 choice backgrounds and various colors in drawing. Compute list functions, exponential functions, statistical and various special functions. Define your own functions and variables, store them on external SD card and reload them back into internal memory. Do various conversions between primary units. Compute properties of various geometric figures.
