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. Prerrequisitos deficientes con software matematico en. That seems to go against some conventions, but so long as you account for the factoredout power of z properly, the math is all correct. If the first argument contains a symbolic function, then the second argument must be a scalar.
