I have a vector I am trying to create that contains the numbers 100-1000 and is incremented by 50. But I want the vector to contain 5 of each increment like [100,100,100,100,100,150,150,150,150,150,200,200,200,200,200,.......,1000,1000,1000,1000,1000]. I created the for loop below but it creates a matrix with 5 rows of 1000. How can I change this for loop to get the vector described above?

for ii=100:50:1000

for j=1:19

x = zeros(1,5)+ii;

ratesX(:,j) = x;

end

在 MATLAB Online 中打开

x = zeros(1,5);
for ii=100:50:1000
    x = [x ones(1,5)*ii];
end
x(x==0) = [] 
x = 1×95
