design an ideal low pass filter

the length of sample is 15024, sampling freq is 11025Hz

I want to get h[n] function such asto get Y=HX with its fourier transforms and get low pass filtered out put y.

Consider refering to the following documentation for help in resolving your problem:

The lowpass function filters an input signal using a lowpass filter. Further, the following example, Lowpass FIR Filter Design shows how to design a lowpass FIR filter using fdesign.

Also, the function, fourier(f) returns the Fourier Transform of f.
