plot for ( x^3+3(x)^2+3x)

                       program:-

1. clf();
2. x=linspace(-1,1,50)
3. y=x.^3+3.*(x.^2)+3.*x;
4. plot(x,y,'r')
5. xgrid(1);

                         output:-

this the output of above program

some important commands used in scilab

introduction to scilab

                                                     SCILAB 

Scilab is an open source, cross-platform numerical computational package and a high-level, numerically oriented programming language. ... Scilab is one of the two major open-source alternatives to MATLAB, the other one being GNU Octave.

THIS SOFTWARE IS USED TO MAKE 3D CURVES 2D CURVES AND MANY MORE FUNCTION 

THIS SOFTWARE IS VERY USEFUL FOR ENGINEERING STUDENTS 

BECAUSE IN MATHS , THIS SOFTWARE PLAYS A VITAL ROLE 

SO I WILL UPLOAD THE PROGRAMS HOW TO WRITE IT 

NOTE :-  THE PROCEDURE OF WRITTING A PROGRAM IN THIS SOFTWARE IS TOTALLT DIFFERENT FROM FROM WHEN WE WRITE ON TURBO C ++ ,DEV, ETC
