convert hC-vectors to lambda-vectors Syntax: lamMatrix = convertHcToLamFromDec(hcMatrix, dec) The hC-vectors in the columns of hcMatrix are converted to the scalar coefficients of a minkowski sum of the structuring elements such that lamMatrix has dec.nS rows and the same number of columns like hcMatrix. See also: obtainDec
