Hi, is there a way to solve this equations simultaneously with Matlab? Here, yj [k] is and integer, S [k] is a 7x1 vector with only 0 and 1 as the elements. Cj is also a 7x1 vector such that Cj = [C1 C2 C3 C4 C5 C6 C7] ' . I need to find each of the C and therefore I need 7 equations to be solved simultaneously. Is this possible with Matlab? Any help is appreciated!
