# exponentsMatrix -- exponents in one or more polynomials

## Synopsis

• Usage:
exponentsMatrix(f_0,f_1,...)
• Inputs:
• (f_0,f_1,...) one or more Laurent polynomials in the same ring.
• Optional inputs:
• Unmixed => ..., default value null
• Outputs:
• (A_0,A_1,...) a sequence of matrices such that the columns of A_i are the exponents of f_i. If either the option Unmixed is set to true or all the matrices A_i are equal, then just one matrix is returned whose columns are all the exponents occurring in at least one of the polynomials.
