An underdetermined system is a system of equations ( algebraic or differential ), the number of equations in which is less than the number of unknowns.
In linear algebra
An indefinite system of linear equations corresponds to a rectangular matrix of coefficients M x N ( M <N, where M is the number of rows, N is the number of columns ). Such a system either has an infinite number of solutions, or has no solutions at all [1] .
