trueFalseParameter

Method of CPNTensor.

Split a signed parameter matrix into the One / MinusOne / Continuous components.

Source: src/tensor/@CPNTensor/CPNTensor.m

Syntax

obj = obj.trueFalseParameter(M)

Description

trueFalseParameter decomposes a single signed parameter matrix M (rows = equations, columns = monomials) into the tensor’s three parameter components and stores them sparsely:

• parameterMatrixOne $= (M == 1)$ — the coefficients equal to $+1$;
• parameterMatrixMinusOne $= (M == -1)$ — the coefficients equal to $-1$;
• parameterMatrixContinuous $= M - \text{parameterMatrixOne} + \text{parameterMatrixMinusOne}$ — every remaining coefficient value.

Subtracting the $+1$ mask and adding back the $-1$ mask removes exactly the $\pm 1$ entries, so parameterMatrixContinuous holds only coefficients whose magnitude is not $1$. This keeps the common unit coefficients as logical masks while storing the general values numerically.

This method backs the two-argument constructor and fromRawMatrices. It sets the parameter components but does not itself refresh the rank.
