SUMMARY
The solution set of a matrix can be classified as a point, line, plane, or cube based on its dimension, which is determined by the nullity of the matrix. The nullity is calculated by first finding the rank of the matrix through row and column operations to achieve echelon form, then subtracting the rank from the total number of columns in the matrix. This method provides a clear understanding of the dimensionality of the solution set.
