Hi all,
I want to perform operations on a cell variable containing different matrices.
I have a cell variable that have 14 different matrices with different length, ie. 2*130, 2*157, etc.
For each cell, I have to perform the following operation.
c = {P1 P2 P3 P4 P5 P6 P7 P8 P9 P10 P11 P12 P13 P14}; % Each P is a different matrix but they are all 2*x long (ie. 130 or 157)
for i = 1:14
WW = sum(c{i},1)>=median(c{i}),1); & sum(c{i},2) >=median(c{i},2); % Condition, my WW variabel should be 1*14 in size, containing the sum of amount of columns that satisfy the condition
end
I know this is dead wrong, but I just want to give you guys an indication of what I want.
Basically, I need my WW to contain the amount of columns that satisfy the condition mentioned in the code. So WW will be the total amount of rows that satisfy the condition.
I want to find the amount of columns that are larger than the median in both row 1 and 2.
Do anyone have a good solution for this?
Kind regards
Anton

Hi Muhammad,
c = {P1 P2 P3 P4 P5 P6 P7 P8 P9 P10 P11 P12 P13 P14};
WW = cellfun(@median,c(1,:),'UniformOutput',false);
This still yield the wrong output.
If I want the median of row 1 for each cell matrix, how do you propose I get that? At the moment I just get the same matrix size as the original, whereas I need just one number that is the median for each cell matrix.
Thanks.

cellfun(@median,cellfun(@(x) x(1,:),c,'UniformOutput',false),'UniformOutput',false)

Hi again Muhammad,
Do you have an idea on how to fix the following:
c = {P1 P2 P3 P4 P5 P6 P7 P8 P9 P10 P11 P12 P13 P14};
med_1 = cellfun(@median,cellfun(@(x) x(1,:),c,'UniformOutput',false),'UniformOutput',false);
med_2 = cellfun(@median,cellfun(@(x) x(2,:),c,'UniformOutput',false),'UniformOutput',false);
WW =sum(cellfun(@(x) x(1,:),c,'UniformOutput',false)>=med_1) & sum(cellfun(@(x) x(2,:),c,'UniformOutput',false)>=med_2) ;
I keep getting this error message: Undefined function 'ge' for input arguments of type 'cell'.
Thanks.
