X ifft y computes the inverse discrete fourier transform of y using a fast fourier transform algorithm. This matlab function returns the fourier transform of f. If y is a vector, then iffty returns the inverse transform of the vector if y is a matrix, then iffty returns the inverse transform of each column of the matrix if y is a multidimensional array, then iffty treats the values along the first dimension whose size does not equal 1 as vectors and returns the inverse transform of each vector. Ive always preferred to work with zdomain equations with positive powers of z, so i do that with iir filters as well. Independent variable, specified as a symbolic variable. Based on your location, we recommend that you select. This variable is often called the complex frequency variable. Transformada y antitransformada z carlos antonio 12122004 23.
