WebMatrix Calculator: A beautiful, free matrix calculator from Desmos.com. WebFinal answer. Step 1/3. ( a) We want a matrix A of order 3 × 3 such that I m ( A) contains the. vector [ 2 1 3]. Since we know that the I m ( A) is span by the columns of a matrix A. Therefore, we can make a matrix A whose one column is this vector then this vector is in the I m ( A). Therefore, the matrix A is. A = [ 2 0 0 1 0 0 3 0 0]

WebApr 16, 2024 · So take a generic 3 by 3 matrix A with entries a,b,c,d,e,f, etc. Next, replace x with the vector (1,0,0) and multiply out the equation. Repeat with x= (0,1,0), and then x= (0,0,1). This forces A to be 6*I, where I is the 3 by 3 identity matrix. Let me know if you need more details. Good luck! Still looking for help?
