Hello all,
I'm writing a for loop with a large number of iterations in it. And at the end of each itaration, I have to set a large array elements to zero. I can do it in the following way:
for i=1:1:LARGE_NUMBER array = zeros(1, ANOTHER_LARGE_NUMBER); % do stuff here with the now zero array
end
However, it looks like to me that this will allocate the memory over and over again at each iteration, which will be a huge performance hit due to the large number of iterations. I can also do this:
array = zeros(1, ANOTHER_LARGE_NUMBER);for i=1:1:LARGE_NUMBER array(:) = 0; % do stuff here with the now zero arrayend
But I'm not sure how this is implemented in MATLAB. Is this the most efficient way of making everything zero in MATLAB?
For instance, it's possible to do the following in C language:
memset(array, 0, sizeof(int) * ANOTHER_LARGE_NUMBER);
Which will efficiently set all values to zero. Is there any equivalent efficient method to do the same in MATLAB?
Any advice will be appreciated.
