System object: dsp.LSPToLPC
Convert input line spectral pairs to linear prediction coefficients
A = step(H,LSP)
A = step(H,LSP) converts the input line spectral pairs in the range (–1,1), LSP, to linear prediction coefficients, A. The input can be a vector or a matrix, where each column of the matrix is treated as a separate channel.
Note: The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object™ issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
