you may have to evaluate the function h(t) at your sampling intervals and then use it. Thus the length of the filter will vary. This is assuming you are using sampled data.
If you want analog response, you should use symbolic toolbox.(or something like that)

Its easy. u should know the sampling rate of the signal. Then you can create a frequency vector like F=linspace(0,1,number of data points/2)*Nyqusit_limit . So find the index of the point in your FT with maximum value( which is your highest frequency) and look the value of F with the same index. So at last u will get the frequency value.

Be clear that in matlab you can do only FFT which is a efficient form of DTFT.
now lets take a analog signal
x(n)= A sin (2*pi*f*t);
( in a PC nothing is analog)...
so lets make it Discrete ... and the sampling freq fs = ( 1/Ts)
lets and fs > 2*fm .. fm = max freq in our input signal
lets take Ts=0.1 (...)

What is yy?
Whatever yy equals, that equation doesn't seem right. Sample rate is usually a constant, dependent on the instrument's A/D converter design, not the length of some array.
