Simple operations with vectors

Hi everyone. I am begining with Matlab and I have a doubt:

Follows my code:

t=0:1/(100*fe):Tmax;
Nped=10
for i=1:Nped
    for 1:lenght(t)
        dist(i)=vp(i)*t;
    end
end

The error that appears is: Unable to perform assignment because the indices on the left side are not compatible with the size of the right

side.

Does anyone knows how can I fix it? Thanks a lot.

What is vp? And what size are dist and vp?

dist(i) is one single number (a scalar), vp(i)*t is a vector of the same length as t.

You can't assign a vector to a scalar element.

Do you mean

t = 0:1/(100*fe):Tmax;
Nped = 10;
for i = 1:Nped
    for j = 1:lenght(t)
        dist(i,j)=vp(i)*t(j);
    end
end

or simply

t = 0:1/(100*fe):Tmax;
Nped = 10;
for i = 1:Nped
   dist(i,:) = vp(i)*t
end

or even simpler

t = 0:1/(100*fe):Tmax;
dist = v.*t

if v is a column vector ?

?

Or maybe

t = 0:1/(100*fe):Tmax;
Nped = 10
for i = 1:Nped
    dist{i} = vp(i)*t;
end

Hi Torsten , Thanks a lot. It works very well !!
