WebDescription. y = interpft(x,n) returns the vector y that contains the value of the periodic function x resampled to n equally spaced points. If length(x) = m, and x has sample interval dx, then the new sample interval for y is dy = dx*m/n.Note that n cannot be smaller than m.. If X is a matrix, interpft operates on the columns of X, returning a matrix Y with the same … WebMALAB基础与实例进阶PPT课件-第10章MATLAB科学计算【学习目标】掌握常用的插值函数和拟合函数的用法会用MATLAB求各类微积分掌握各种线性方程组和非线性方程组的求MATLAB ... x为一个矩阵时，interpft对x按列进行数据插值 ，返回矩阵y的行数为n，列数与x ...
