Scilab understands matrices, vectors as already defined data types. It
also understands polynomials. It has inbuilt functions to compute
eigen values, eigen vectors of matrices, it can find determinant and
inverse of the matrix. It can find roots of the polynomial. Real roots
as well as complex roots of the polynomial( if exists).

It can remember previously calculated values as well as it allow user
to store calculated results in text file. It understand numerical
values for pi, e, i etc.

It works on Linux, Mac, and on windows.

It is open source software which can be used as a calculator
initially. And for advanced use afterwards.
