Question

function[prob,flop]=Matlab(a,b)

a=[1,2,3];
b=[7,8,9];

if (length(a)~=length(b))
disp("it doesn't make sense");
end

prob=0;
flop=0;

for i=1:length(a)
prob=prob+a(i)*b(i);
flop=flop+2;
end
disp(prob);
disp(flop);

What is wrong with my code? it only run the disp(prob) and it doesn't run the disp(flop)

here is what I got

ans =

50

However, if I take % for the function line, it shows

50

Answer 1

function dummy
clc;
clear all;
a=[1;2;3];
b=[7;8;9];

[prob,flop]=Matlab(a,b);
function[prob,flop]=Matlab(a,b)

if (length(a)~=length(b))
disp("it doesn't make sense");
end

prob=0;
flop=0;

for i=1:length(a)
prob=prob+a(i)*b(i);
flop=flop+2;
end
disp(prob);
disp(flop);
end
end

>>

you should not give a=[1,2,3]; b=[7,8,9]; .. you should use by this way a=[1;2;3]; b=[7;8;9];

function dummy
clc;
clear all;
a=[1,2,3];
b=[7,8,9];

[prob,flop]=Matlab(a,b);
function [prob,flop]=Matlab(a,b)

if (length(a)~=length(b))
disp("it doesn't make sense");
end

prob=0;
flop=0;

for i=1:length(a)
prob=prob+a(i)*b(i);
flop=flop+2;
end
disp(prob);
disp(flop);
end
end

$$$$$$$$ Note: this way also its give same answer
