%% Miguel De Gracia. 19481379. Lab Assignment 5. Section 22 % %% Problem 1a % x=2; y=3; x x > y x < y x >= y x <= y x == y x ~= y %The problem returns a 1 if the statement is true, and a 0 if the statement %is false. % %% Problem 1b % y = [1 3; 5 2]; y x > y x < y x >= y x <= y x == y x ~= y all(y==x) any(y==x) find(y<=x) %In this case since y is now a matrix, it compares x to every element of y %and performs the same task as the previous problem. For all or any it does %so by comparing it according to each column.Find returns the indeces in %which the logical statement is true. % %% Problem 1c % x = [2 4; 5 1]; x x > y x < y x >= y x <= y x == y x ~= y all(y==x) any(y==x) find(y<=x) %Since both x and y are now matrices, it compares the elements and %evaluates the logical command at that element, returning an answer in %matrix form as well. % %% Problem 1d % a=1; b=0; c=1; a a | b a | c & b
