## FAQs

**How do you calculate column space?** Column space refers to the span of the columns of a matrix and can be calculated using linear algebra techniques. You would typically perform row reduction (Gaussian elimination) on the matrix to find its row echelon form or reduced row echelon form (RREF). The number of nonzero rows in the RREF will give you the dimension of the column space.

**How do you find row space and column space?** Row space is the span of the rows of a matrix, and column space is the span of its columns. To find the row space, you would perform row reduction on the matrix to obtain the row echelon form or RREF. For the column space, perform column reduction to find the RREF and then identify the columns with leading 1’s in the RREF. These columns form the basis for the column space.

**What is span of column space?** The span of the column space of a matrix is the set of all possible linear combinations of its columns. In other words, it represents all the vectors that can be created by taking different combinations of the columns of the matrix.
