help with this

You can't just place two cells next to each other like that - you need a comma or semicolon to separate them. Try replacing }{ with }, {

Actually I don't know why you're using cells anyway. Why not just use parentheses so you have normal, regular numbers, not cells. Cells are not for the faint of heart beginner MATLAB programmers.

thanks man i got the solution by removing the unnecessary brackets.

I don't know what you are trying to achieve, but i think you should start with perusing this... http://matlab.wikia.com/wiki/FAQ
R1=1;
L=10e-3;
C1=10e-6;
R2=10;
A=[(-R1/L)*(-1/L);(1/C1)*(-1/(R2*C1))];
B=[(1/L);0];
C=[0 1];
D=0;

and I am trying to get the step response of R,L,C circuit using steady state equation.
