Part I. True or False. Circle one. 1. Tor F: The command 'clc' removes all the variables from the Workspace. 2. Tor F: If a=[1, 2, 3]' then the expression (a'; a') cannot be used. 3. Tor F: If a=[1, 2, 3] and b=[3; 2; 1] then b*a returns a scalar. 4. Tor F: Use ['abc'; 'ef'; 'xyz'] can create a new string matrix. 5. Tor F: 3i is the same as i3. 6. Tor F: If A and B are two matrices with different dimensions then size(length(A)) is equal to size(length(B))
