Hello,

myfunc1 takes in a vector and gives out a vector as expected.

but myfunc2, which has a for loop, takes in a vector and gives out a scalar value of 1.

can you please help me to fix myfunc2 so that it gives out a vector, which is a vector of :

(summation from 1 to 1, summation from 1 to 2, summation from 1 to 3, ..., summation from 1 to 10)

thank you //:-)

---------

clear all

clc

x=[1:10];

%myfunc2(x)

myfunc1(x)

function [y2]=myfunc2(p)

k=0;

for t=1:p

k=k+t;

end

y2=k;

%y2=p+1;

end

function [y1]=myfunc1(p)

y1=p+1;

end

Is this what you are trying to do?

x = 1:10;
result = myfunc2(x)
result = 1×10
     1     3     6    10    15    21    28    36    45    55
function [y2]=myfunc2(p)
k=0;
y2 = [];
for t = 1:length(p)
    k = k + t;
    y2 = [y2 k];
end
end
