MATRIX("METZLER",order)
- is the order of the Metzler matrix.
is the order of the Metzler matrix.Description
- This function gives the matrix of order 3 with the metzler properties.
- A matrix is called Metzler if all of its elements are non-negative except for those on the main diagonal, which are unconstrained.
- i.e., The off diagonal values must be "+" and main diagonal values "+","-" or "0".
- Also Metzler is also called as quasi positive or essentially nonnegative.
- The exponential of a Metzler matrix is a nonnegative matrix because of the corresponding property for the exponential of a nonnegative matrix.
- A Metzler matrix has an eigenvector in the nonnegative matrix because of the corresponding property for nonnegative matrices.
- In Calci, users need a metzler matrix with various values, then the syntax is MATRIX("metzler").
- Otherwise users need a matrix with values 0,1 and -1, then the syntax is : MATRIX("metzler:negzeropos")
