Graphing scientific calculator. MathPad is a general purpose graphing scientific calculator. It uses a text worksheet rather than simulating buttons on a hand held calculator. This live scratchpad interface allows you to see and edit your entire calculation. In addition to being a handy little calculator, MathPad can also take on larger problems. Simple plotting allows quick visualization of results. General purpose arrays allow calculations involving vectors, complex numbers, matrix algebra etc. 2D arrays can be displayed as grayscale or color images. Several examples are included showing such things as equation solving, curve fitting, vector calculations and numerical solution of differential equations. Plug-in modules provide specialized capabilities in areas such as engineering, finance, statistics, linear algebra, data analysis, sound and image processing.
