Saving selected array of data from set of output array

2 visualizaciones (últimos 30 días)
Hello
My problem looks similar to the following -
for ii = 1:1000
x = cos(ii)*{a 1by1000 array}
end
Now, out of this 1000 results for x, i want to save only few data sets; like at ii=1,100,200,300....,1000. The problem that i am handling in real has millions of loops but i need just a few array. Can anyone please help me to get a solution.
Thanks in advance.

a=rand(1,1000);
cii=cos([1 100:100:1000]),
x=bsxfun(@times,a,cii') % result = array 11x1000

Hi Azzi
You seem to have removed the codes for saving the arrays selectively. Could you please post that again.
Thanks

create an array of the values you need at different locations eg : i=1:100: number_of_values
then create a new array to store them eg: for k= 1:length(number_of_values) req_values(k)= all_values(i); end
