Note that 'a'=97, 'A'=65, and '0,:48. Part I. True or False. Circle one. (20 Points - 2 Each) 1. Tor F: The command 'clc' removes all the variables from the Workspace. 2. Tor F: The expression 'a'+1 returns 'b' 3. T or F: If a=[1, 2, 3], then the expression [a"; al cannot be used. T or F: If a=[1, 2, 3], then a, * a returns a scalar 5. T or F: If a=[1, 2, 3] and b=[32; 1] then b+a can be used. 6. Tor F: Use ['abc, 'ef; 'xyz] can create a new string matrix 7. Tor F: 3i is the same as i3 8. Tor F: I f A and B are two matrices with different dimensions then size(length(A)) is equal to size(length(B))
