The basic syntax for resample is. y = resample (x,p,q) where the function resamples the sequence x at p/q times the original sample rate. The length of the result y is p/q times the length of x.

Resampling of Discrete-Time Systems. Resampling consists of changing the sampling interval of a discrete-time system. This operation is performed with d2d. For example, consider the 10 Hz discretization Gd of our original continuous-time model G. You can resample it at 40 Hz using:

d = size (X) returns the sizes of each dimension of array X in a vector d with ndims (X) elements. If X is a scalar, which MATLAB regards as a 1-by-1 array, size (X) returns the vector [1 1]. [m,n] = size (X) returns the size of matrix X in separate variables m and n. m = size (X,dim) returns the size of the dimension of X specified by scalar dim.

Signal Analyzer uses the Signal Processing Toolbox™ function resample to perform the resampling. The available options are:The resample function only takes double arguments, although they can be vectors or matrices. You would likely have to extract the timeseries object to a double vector (or matrix), or loop through the individual rows (or columns) of your timeseries object. The loop is likely the best option.Input array, specified as a real-valued or complex-valued scalar, vector, matrix, N-D array, or gpuArray object.

resampling methodology and the Resampling Stats in MATLAB soft-ware. We attempt to provide enough conceptual background and de - nition of statistical terms to make the book self contained. \Self con-tained" is not, however, the same thing as \systematic" or \comprehen-sive." This book does not cover all methods of analysis in statisticaland the test passed, so I think it works! MATLAB also includes the ramp down in its output (running zeros through the filter) so that the output has length ceil(Int, input*ratio). I think the resample function should probably do this on its own, but if I add the zeros to the end of the input, the result matches for the remaining points as well.Create a vector of data y and another vector with the x -coordinates of the data. x = -4:4; y = [0 .15 1.12 2.36 2.36 1.46 .49 .06 0]; Interpolate the data using spline and plot the results.

When the specified sample rate and the nominal sample rate, corresponding to the FFT size, do not match, the ...The resample function is designed to convert sample rates to either higher or lower rates. As a consequence, the frequency cutoff of the anti-aliasing filter is set to the Nyquist frequency of the input or output sample rate (whichever is lower). This default setting allows the resample function to cover a wide range of applications. Fortunately, matlab has a function 'fminsearch' that uses a sophisticated numerical analysis technique that can find the minimum of a function like this - as long as it's reasonably continuous and well behaved.
