given a matrix, find its cofactor matrix https://en.wikipedia.org/wiki/Minor_(linear_algebra)#Inverse_of_a_matrix
Why is there a value 4.000000000000001 in the cofactor matrix of problem 4? The matrix is composed entirely of integers, so the cofactors should all be integers as well.
@william .. sorry man-- i overlooked .. i've corrected it now.
sth related to the determinant function- matlab provided that answer. i didn't see that
Swap the first and last columns
Reverse the vector
Is this matrix orthogonal?
remove numbers from a string
ZigZag - 04
Take a binary number as input,rearrange it in any manner such that its value is greater than the original one.output should be all the possible values in decimal.
