Hello,
I am having trouble converting a cell with numbers in string format to a column vector. The cell is as follows
data={'10';'1';'40';'5'}
I would like to convert this to a vector
new_data=[10;1;40;5]
When I try to use cell2mat(cell), this returns an error: Dimensions of matrices being concatenated are not consistent.
The only work around I have found thus far is the following
for ii=1:length(data)
new_data(ii,1)=(str2num(data{ii}));
end
Where new_cell is the desired vector. This would not be a problem to use, but the real cells contain many hundreds of numbers in string format, and the loop is eating too much time.
Is there any other workaround for this?
Thanks, Carmelo

data={'10';'1';'40';'5'} ;
iwant = cellfun(@str2num,data);
The above cellfun uses loop inside. You may check with this also:
str2double(data)
