[smriti naik]

hey,i want a program on matrix operation using function in c++ which includes a menu displaying choice for add,subtract,mu ltiply and exit

[horace1]

have a look at opensource programs on matrix operations, e.g.

http://www.ibm.com/developerworks/opensource/library/l-matrix.html

if it is numerical computations you are interested in look at GNU Octave
