how to fix "In an assignment A(I) = B, the number of elements in B and I must be the same"

This is the code I wrote to store values in a vector but it is not working for some reason. I have realized that I am adding vector to a scalar but I am not sure how to fix it!

CODE ======================================================================

y1 = 1;

deltT = 1;

for t1=1:1:10;

y1(t1) = y1 + t1*deltT

end

==================================================

ERROR MESSAGE

y1 =

     2

y1 =

     2     4

In an assignment A(I) = B, the number of elements in B and I must be the same.

Error in Untitled (line 17)

y1(t1) = y1 + t1*deltT ================================================================================

Help would me much appreciated! Thanks!

You should not use same name for variable and array. You are using "y1" as variable as well as an array later in for loop. So you can do it correctly this way:

y = 1; 
deltT = 1;
for t1=1:1:10
    y1(t1) = y + t1*deltT
end

or in a better way

y = 1;
deltT = 1;
t1 = 1:10;
y1 = y + t1 * deltT

Good luck!

Thanks I actually troubleshooted it a little more and ended up with fixing it. I used this code

y1 = 1;

deltT = 1;

for t1=1:1:10;

    y1(t1) = y1(t1-1) + t1*deltT

Again, thank you so much for your help!
