What is the purpose for writing two output arguments in the code? i.e. [area, tri_area]
If the user is calling the area of a triangle wouldn't that be only one output argument?

function area = tri_area(b,h)
area = 0.5*b*h;
end
From the command window
A = tri_area(3,2)

Have you considered adding disp statements so you can see what parameters are being passed for the random input case?

function
function [area] = tri_area (b,h)
tri_area = (0.5)*(b)*(h)
code to call your function
tri_area(2,3) %any random input

result = tri_area(2,3) %any random input
tri_area = 3
Output argument "area" (and maybe others) not assigned during call to "solution>tri_area".
function [area] = tri_area (b,h)
tri_area = (0.5)*(b)*(h)
end
