this is the error i am getting

Error in solve (line 357)
       warnIfParams(parameters, conditions);
Error in matlab (line 8)
[d]=solve(e);

behind this line e= diff(e, b) == 0; the meaning is to get a an equation by differentiating e with respect to b and solve to it

Ashok, that doesn't look like the full text of the error message. Copy and paste all the text displayed in red. The exact text of the error message likely will be useful in determining the exact cause of the problem and how to correct it.

And just stylistically: while calling your script matlab.m shouldn't cause any problems, I recommend using a more descriptive and more easily discoverable name. Something like codeForProblem2.m would more clearly indicate the code's purpose at a glance in your OS's file system UI.
