Hello, I am trying to populate a 60x6 matrix with random values for different variables (force, torque, radius, etc) as its columns. Each of the variables must iterate 60 times and fall between a given range. I attempted to make a column vector for each variable and implement them into the matrix, however I am receiving an error when doing so.
Pop=ones(60,6);
F=ones(60,1);
P=ones(60,1);
T=ones(60,1);
r=ones(60,1);
t=ones(60,1);
range of values
x=1;
while x<61
F(x)=99000.*rand(60,1)+1000;
P(x)=999000.*rand(60,1)+1000;
T(x)=4990.*rand(60,1)+10;
r(x)=0.04.*rand(60,1)+0.05;
t(x)=0.0008.*rand(60,1)+0.0001;
Pop=(:,1)= F(60,1);
Pop=(:,2)= P(60,1);
Pop=(:,3)= T(60,1);
Pop=(:,4)= r(60,1);
Pop=(:,5)= t(60,1);
x=x+1
end

for i = 1:60
F=99000.*rand(60,1)+1000;
P=999000.*rand(60,1)+1000;
T=4990.*rand(60,1)+10;
r=0.04.*rand(60,1)+0.05;
t=0.0008.*rand(60,1)+0.0001;
pop = [F P T r t]
end

Thanks. I was getting 0 values on the last two columns but I turned the matrix into a table. Ended up being the last two columns had very small values.

Should be
F(60,1)=Pop(:,1);
P(60,1)=Pop(:,2);
T(60,1)=Pop(:,3);
r(60,1)=Pop(:,4);
t(60,1)=Pop(:,5);

Use proper declaration properly in order to avoid the error like the above. Anyhow there are many errors in your code just wanted to point out this mistake.
