I have the following code, i am entering value manually
i want to do it using for loop how can i do that and save data in 1x1000 in mat file
prfDS = [200 500 800 1000 800 900];
n_pulsesDS = [120 400 1200 1500 600 350];
prfDS(1:120) = 200
prfDS(121:520) = 500
prfDS(521:1720) = 800
prfDS(1721:3220) = 1000
prfDS(3220:3820) = 800
prfDS(3820:4720) = 900
scatter(1:length(prfDS),prfDS)

The last interval shown in your example indexing is inconsistent with the provided data:
cumsum([120,400,1200,1500,600,350])
ans = 1×6
120 520 1720 3220 3820 4170

The simple and efficient MATLAB approach would be to use REPELEM, for example:
val = [200,500,800,1000,800,900];
num = [120,400,1200,1500,600,350];
out = repelem(val,num)
out = 1×4170
200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200 200
numel(out)
ans = 4170
