Hello Everyone i hope you are doing well. I have the following dataset
One has 30 samples ( Shape 30x1) and other has 115 samples(Shape 115x1) . My network is trained on shape (1000x1). I want to repeat elements of the array from start to complete 1000 samples.
The samples varries (10-1000) like shape is 10x1 or 388x1
for example the data is look like that, so it will repeat from start to complete 1000 samples
How can i do it in MATLAB

Ran in:
You can use repmat() to replicate the array (or repelem() to repeat each element of the array) enough times to get at least 1000 rows, then remove the extra.
load('dataset1.mat');
load('dataset2.mat');
N_needed = 1000;
dataset1_new = repmat(dataset1,ceil(N_needed/size(dataset1,1)),1);
dataset1_new(N_needed+1:end,:) = [];
dataset2_new = repmat(dataset2,ceil(N_needed/size(dataset2,1)),1);
dataset2_new(N_needed+1:end,:) = [];
whos
Name Size Bytes Class Attributes N_needed 1x1 8 double ans 1x37 74 char dataset1 30x1 240 double dataset1_new 1000x1 8000 double dataset2 115x1 920 double dataset2_new 1000x1 8000 double

EDIT — (11 Mar 2022 at 6:14)
There is one other way I can think of to do this, however it involves some compromises since it ‘squeezes’ the 1020-element vector into 1000 elements, or ‘stretches’ the 990-element vector to 1000 elements (both will work with this code, although I am only showing one here):
x1 = 1:numel(stretch1); % Match 'stretch1' Length
xq = linspace(1, numel(stretch1), DesiredLength); % 'DesiredLength' Interpolation Vector
squeeze1 = interp1(x1, stretch1, xq); % Interpolate (Decimal Fractions)
squeeze1i = round(squeeze1); % Integers Only
figure
subplot(3,1,1)
plot(x1, stretch1)
xlim([1 numel(stretch1)])
grid
title(sprintf('Original Vector, Length = %d',numel(stretch1)))
subplot(3,1,2)
plot(xq, squeeze1)
xlim([1 numel(stretch1)])
grid
title(sprintf('Squeezed Vector, Length = %d',numel(squeeze1)))
subplot(3,1,3)
plot(xq, squeeze1i)
xlim([1 numel(stretch1)])
grid
title(sprintf('Squeezed Integer Vector, Length = %d',numel(squeeze1i)))
