Writing the built in matlab function in simple code(like for loop, etc.)
显示 更早的评论
Hi guys,
I'm trying to do the same concept of what my code below does, but in a simple approach with different way.
My code in MATLAB is:
y=[1 2 3 4]; %first input
OccurancesParameter= 5; % second input , it's always unsigned integer number greater than zero - it's number occurances for each value in the array y
output=repelem(y, OccurancesParameter); % gives me an array according to the repeated Occurance parameter ..
So I want to do the same concept of what my code above does, but simple approach/way in MATLAB, like using for loop or any other simple way, and not using the built in function repelem().
Could anyone please help me out on this? appreciated!

Jimmy, try this:
y=[1 2 3 4]; % First input
OccurancesParameter= 5; % second input , it's always unsigned integer number greater than zero - it's number occurances for each value in the array y
output=repelem(y, OccurancesParameter); % gives me an array according to the repeated Occurance parameter ..
y2 = zeros(1, length(y) * OccurancesParameter);
for k = 1 : length(y)
thisy = y(k);
for k2 = 1 : OccurancesParameter
index = (k - 1) * OccurancesParameter + k2;
y2(index) = thisy;
end
end
y2 % Display in command window

y=[1 2 3 4];
OccurancesParameter= 5;
m = y(:)' .* ones(OccurancesParameter, 1);
output = m(:)'
For Matlab releases prior to r2016b,
y=[1 2 3 4];
OccurancesParameter= 5;
m = bsxfun(@times,y(:)', ones(OccurancesParameter, 1));
output = m(:)'
