Legacy Name: buffer
Resizes an input vector into a matrix.
Name | Description |
---|---|
x | Specifies the input vector you want to resize. x is a real or complex vector. |
n | Specifies the number of data elements in each column of Y. |
p | Specifies the length of the overlap between adjacent columns. If p is greater than 0 and less than n, the overlap between adjacent columns equals p elements. If p is less than 0, LabVIEW skips -p elements between adjacent columns. If n is less than or equal to p, LabVIEW returns an error. |
option | Specifies the option to use to resize the matrix. If p is greater than 0 and less than n, option can be 'nodelay' or a vector of p elements that LabVIEW inserts at the beginning of the input vector x. If option is 'nodelay', LabVIEW does not insert any values at the beginning of x. If p is less than 0, option is an integer that specifies how many elements to delete from the beginning of x before LabVIEW constructs the matrix. |
Name | Description |
---|---|
Y | Returns the output matrix. If there are not enough elements in x, LabVIEW pads the last column of Y with zeros. |
R | Returns the residual vector if there are not enough elements to form a complete last column of Y. |
L | Returns information about the elements in the residual vector R. If p is greater than 0, L is a vector that contains the samples in R that LabVIEW did not pad with zeros. If p is less than 0 and R is empty, L is a scalar that indicates the number of missing elements LabVIEW needs to form a complete column with a length of n - p. If p is less than 0 and R is not empty, L equals 0. |
