As such, they will be elements of Euclidean space, and the column space of a matrix will be the subspace spanned by these vectors. What is the dot product of vectors? $$ \text{proj}_{u_1}(v_2) = v_2$$ To solve a math equation, you must first understand what each term in the equation represents. Step 2 Let v 2 = u 2 u 2, v 1 v 1 2 v 1 . They are: For instance, say that you have a matrix of size 323\times 232: If the first cell in the first row (in our case, a1a_1a1) is non-zero, then we add a suitable multiple of the top row to the other two rows, so that we obtain a matrix of the form: Next, provided that s2s_2s2 is non-zero, we do something similar using the second row to transform the bottom one: Lastly (and this is the extra step that differentiates the Gauss-Jordan elimination from the Gaussian one), we divide each row by the first non-zero number in that row. If the constants are all equal to 1, then the set of vectors is Example: how to calculate column space of a matrix by hand? You've known them all this time without even realizing it.
