## Question:

Tag: arrays,matlab,conditional,cell

Hello I am trying to create a cell array that should look something like this.

``````'3/7/2014'  '209.167.128.156'   1037
'3/13/2014' '204.205.57.137'    8
'3/18/2014' '209.167.128.156'   164
'3/27/2014' '216.178.43.209'    825
``````

But the problem is when I run my code I get a cell array that looks like this

``````{1x3cell} {1x3 cell} {1x3 cell} {1x3 cell} {1x3 cell]
``````

Here is my code:

``````cell = {};
month = 'March';
text(1,:)= [];
fanta = text(:,1);
[row col] = size(fanta);
a = 1;
for i = 1:row
coke = fanta{i};
[first rest] = strtok(coke, '/');
if strcmp(first, '1') && strcmp(month, 'January')
cell{i} = raw((a+i), :);
end
if strcmp(first, '2') && strcmp(month, 'February')
cell{i} = raw((a+i), :);
end
if strcmp(first, '3') && strcmp(month, 'March')
cell{i} = raw((a+i), :);
end
if strcmp(first, '4') && strcmp(month, 'April')
cell{i} = raw((a+i), :);
end
if strcmp(first, '5') && strcmp(month, 'May')
cell{i} = raw((a+i), :);
end
if strcmp(first, '6') && strcmp(month, 'June')
cell{i} = raw((a+i), :);
end
if strcmp(first, '7') && strcmp(month, 'July')
cell{i} = raw((a+i), :);
end
if strcmp(first, '8') && strcmp(month, 'August')
cell{i} = raw((a+i), :);
end
if strcmp(first, '9') && strcmp(month, 'Sepetember')
cell{i} = raw((a+i), :);
end
if strcmp(first, '10') && strcmp(month, 'October')
cell{i} = raw((a+i), :);
end
if strcmp(first, '11') && strcmp(month, 'November')
cell{i} = raw((a+i), :);
end
if strcmp(first, '12') && strcmp(month, 'December')
cell{i} = raw((a+i), :);
end
end
cell = cell(~cellfun('isempty', cell))
``````

What am I doing wrong and how can I fix it. Thank you.

First, you should never call a variable `cell`, since it is the name of a built-in Matlab function. This is bad, you should be punished for this :-)

Let's say you have replaced all `cell`'s by `C`. Then, you should initially define `C` by

``````C = cell(0,3);
``````

and replace all your

``````C{i} = ...
``````

by

``````C(i,:) = ...
``````

Last point: the last column will be made of strings an not numbers. You may should consider to use the function `str2double` somewhere in your code if you really want to have numbers in this column.

Best,
