Question

A = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20]

In MATLAB. Use a fully vectorized code (ie. no loops) to determine when the numbers have increased to at least 15 in the above array. Report answer to command window.

Answer 1

MATLAB CODE:

A = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20];
% Find position after which numbers increased to at least 15
pos = length(A) - length(find(A >= 15)) + 1;
fprintf("From position %d, numbers increased to at least 15 in the above array\n", pos);

OUTPUT:
