How to split an array into smaller unequal-sized arrays dependend on array-column values

8 views (last 30 days)
I have an array of 2 column and about 31,000 rows. One of the two columns depicts a spatial coordinate on a grid the other one a dependent parameter. What I want to do is the following:
I need to split the array into smaller parts defined by the spatial column; let's say the spatial coordinate are ranging from 0 to 500 - I now want arrays that give me the two column values for spatial coordinate 0-10, then 10-20 and so on. This would result in 50 arrays of unequal size that cover a spatial range from 0 to 500.
Thank you

Histcounts can be used to pin the data the way you want.
[~,~,BIN] = histcounts(mainArray(:,1), 0:10:500)
subArray1 = mainArray(bin==1,2);
subArray2 = mainArray(bin==2,2);
subArray50 = main array(bin==50,2)

I don't think OP should necessarily create individual named variables. I would actually recommend indexing into their main array using the bin indexes as needed rather than actually splitting up the data, but I wanted to show them how they would do the indexing in as simple a manner as possible and to answer their direct question.
