Repeat copies of array elements collapse all in page Syntax u = repelem(v,n) B = repelem(A,r1,...,rN) Description u= repelem(v,n), wherevis a scalar or vector, returns a vector of repeated elements ofv. Ifnis a scalar, then each element ofvis repeatedntimes. The length ofuisleng...
Repeat the computation using the default values of the spectrogram function: Divide the signal into segments of length M=⌊Nx/4.5⌋, where Nx is the length of the signal. Window each segment with a Hamming window. Specify 50% overlap between segments. To compute the FFT, use max(256,...
Number of times to repeat the input array in the row and column dimensions, specified as an integer value. If n is 0 or negative, the result is an empty array. Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 r1,...,rN— Repe...

The optional input n (format repeat count) specifies the number of times the format string is to be used or the number of lines to be read, whichever happens first while reading. The former is equivalent to requesting that the data output vectors should be of length N. Note that when rea...

Number of times to repeat the clustering, each with a new set of initial cluster centroid positions. kmeans returns the solution with the lowest value for sumd. You can supply 'replicates' implicitly by supplying a 3D array as the value for the 'start' parameter. 'start' Method used to ...
