help with this

Answer 1

[Image Analyst]

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 }, {

[Image Analyst]

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.

Answer 2

[Ilham Hardy]

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;

[Harry]

"A" is a matrix of 2*2 and it is giving a error as I have mentioned earlier

[Ilham Hardy]

Did you try my answer?

You need to differentiate the use of curly brackets {} and normal brackets ()

[Harry]

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

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