x = -10 : 0.01 : 10;
y = (exp(x)./ sin(x)) + 0.3;

You can use diff to get numerical approximations of the derivatives and apply stationary point criteria based on those.
If needed, you could then use fzero to find roots of the derivatives using what you got from diff as initial guesses. This would refine the estimates of the stationary point locations to better than your 0.01 sampling interval.
