Filling a cell array
in [Matlab]
|
From: Judas Magnus on 4 Apr 2010 14:46 Say that I have a cell array cell1 = (5,5) I want to fill all the containers with the number "1". How can I do this, also if there was a name inside one of the containers then is it possible to check to see if there is an empty container and assign "1" to all of them?

How can I do this, also if there was a name inside one of the containers then is it possible to check to see if there is an empty container and assign "1" to all of them? one of the solutions c=cell(5,5); c(1,1)={'a'}; c(2,2)={'b'}; ix=cellfun('isempty',c); c(ix)={'1'} %{ % c = 'a' '1' '1' '1' '1' '1' 'b' '1' '1' '1' '1' '1' '1' '1' '1' '1' '1' '1' '1' '1' '1' '1' '1' '1' '1' %} us

From: Judas Magnus on 4 Apr 2010 17:19 hmmm is there a way to AFTER filling all the containers with "1" to replace all of them with the word "cool" ? for example: cf = cellstr(char('Meat','Meatz','Meat1','Meat2','Meat3')) c = cell(5,5) r = randperm(numel(c)); r = r(1:numel(cf)); c(r) = cf(randperm(numel(cf))) %I want to replace all those of meat in the cf array to be replaced by "cool"

If you use '' for empty cell elements and run regexprep() on cell array, it should work: clc cf = cellstr(char('Meat','Meatz','Meat1','Meat2','Meat3')); c = cell(5,5) c(:)= {''}; %!!! r = randperm(numel(c)); r = r(1:numel(cf)); c(r) = cf(randperm(numel(cf))) %I want to replace all those of meat c1 = cellfun(@(c) regexprep(c, '^Meat$', 'cool'), c, 'UniformOutput', 0) %!!!
