b = firls(30,[0 .1 .2 .5]*2,[1 1 0 0]);
fvtool(b);
Obviously you have to specify more than the order. You have to give your frequencies and the amplitudes you wish at those frequencies. I have just used some values above.
Please read the reference page for firls.
Also, I'm assuming that you mean this filter and not the LMS adaptive FIR filter.

fir1 uses the window method. That is a different filter design method. The window method is described in any DSP book.
