Let A be an m × n matrix. Enable the column rank of A be r, and let c1, ..., cr be any foundation to the column Place of A. Position these as the columns of the m × r matrix C. Each and every column of the may be expressed for a linear combination of the r columns in C. Which means that There exists an r × n matrix R these that A = CR. R could be the matrix whose ith column is shaped within the coefficients giving the ith column of A for a linear combination of the r columns of C. Basically, R would be the matrix which incorporates the multiples for the bases in the column Place of A (that's C), which happen to be then used to type A in general.

Further elementary column functions allow for Placing the matrix in the shape of an identity matrix probably bordered by rows and columns of zeros. Again, this modifications neither the row rank nor the column rank. It's instant that both the row and column ranks of this resulting matrix is the amount of its nonzero entries.
