I want to simulate linear change, can you help me?

Hi,

I am going to simulate data with linear change. I have already done a simple simulation with only a random error-part like this:

-

function simulation1_values=simulation1(h_error,grand_mean,Nu)

rng('shuffle')

grand_mean=74.3;

Nu=72;

simulation1_values=zeros(Nu,1);

Q=length(simulation1_values);

for r=1:Q

    simulation1_values(r)=0;
    h_error=randn;
    simulation1_values(r)=grand_mean+h_error;
end

end

-

Now I want to include a part that gives a linear change from say 74.3 to 90. Can someone help me? :)

Thank you!

Try linspace

startingValue = 74.3; % Whatever you want.
endingValue = 90; % Whatever you want.
numberOfElements = Q; % Whatever you want.
linearValues = linspace(startingValue, endingValue, numberOfElements);
