linspace: handle ranges with equal Inf endpoints (bug #53489) * CMatrix.cc (ComplexMatrix::linspace): Change delta calculation to yield 0 if endpoints are the same, otherwise calculate delta as normal. * CRowVector.cc (ComplexRowVector::linspace): Likewise. * dMatrix.cc (Matrix::linspace): Likewise. * dRowVector.cc (RowVector::linspace): Likewise. * fCMatrix.cc (FloatComplexMatrix::linspace): Likewise. * fCRowVector.cc (FloatComplexRowVector::linspace): Likewise. * fMatrix.cc (FloatMatrix::linspace): Likewise. * fRowVector.cc (FloatRowVector::linspace): Likewise. * data.cc (Flinspace): Added Matlab compatibility tests. * logspace.m: Added same tests as in linspace containing Inf in endpoints.
