The variable in is displayed as matrix: in =
    0.2788
    0.2186
    0.2170
    0.2435
    0.2156
    0.2291
    0.2265
    0.2523
    0.2930
    0.3196
    0.3299
    0.2958
    0.2279
    0.2180
    0.1477
    0.1014
    0.1281
    0.1473
    0.1485
    0.1944
    0.1926
    0.1361
    0.0806
    0.5136
I want to do the following: I want to subtract the variable "in" from "out" in such a manner that the first 24 rows of each column of every table of variable "out" is subtracted from variable "in", then the next consecutive rows of table "out" subtracted from table "in", then the next consecutive rows and so on until all rows are completed. The example below illustrates what I want to do:
row 0-24 from every table of variable "out" minus 24 rows from Table "in" row 25-49 every table of variable "out" minus 24 rows from Table "in" and so on.
I want the result to be a positive value so absolute value. At the same time this is a labor intensive process so I want this to be performed quickly. How can I do this?
thanks

Look at this example
out={rand(48,24);rand(72,24)}
in=rand(24,1)
res1=cellfun(@(x) bsxfun(@minus,permute(reshape(x,24,24,[]),[2 1 3]),in),out,'un',0)
res=cellfun(@(x) reshape(x,[],24),res1,'un',0)
