Document Summary

Eng ek 103: computational linear algebra, fall 2022. This assignment is about vector spaces (lecture 12 and sec. Justify your answer. b) d: below are shown two cases of a matrix a and an echelon form of a. Find a basis for col a (column space of a) and nul a (null space of a). Refer to examples from lecture 13 and your textbook (vector elements should be whole numbers, don"t just copy a matlab result!: compute the determinant for each matrix below using the cofactor expansion method. Choose a row or column that requires the least computation (relevant mostly for parts c and d). Indicate whether any of these matrices is singular. Show your steps for credit. d: let a and b be 4x4 matrices with det a=4 and det b =-3. Be sure to keep track of effects of row reduction steps on the determinant. 1) (a)x10,+x2vc +x3v3=u m = tv, m vs 23 =faicos ii] .
