Convert values in the cell to array using cell2mat

I have 72 x 1 cell named let's say output1, each cell got 8 x 1 entries. Now, I intend to store each 8 x 1 entries into the seperate array, such that finally I will get 8 x 72 array.

I used cell2mat(output1) Instead of 8 x 72 array, it stores all entries in the single column i.e. i got 576 x 1 , please let me know how to get this ..

The robust approach:

out = horzcat(output1{:})

Hi Stephen,

Tried the same, got the below error msg.

Attached here the output1 cell for your reference

Error using horzcat
Dimensions of arrays being concatenated are not consistent.

Almost all of the cells contain column vectors of eight elements, but a few of them have five/six elements:

>> S = load('matlab.mat')
S = 
    output1: {72x1 cell}
>> nmr = cellfun('size',S.output1,1);
>> unique(nmr)
ans =
     5
     6
     8
>> hist(nmr,unique(nmr))

It is not possible to horizontally concatenate column vectors with different numbers of elements. You will have to fix your data, or use a tool that pads the vectors automatically for you, e.g.:

"...each cell got 8 x 1 entries..."

is what you wrote in your question, but this statement does not match the data you uploaded.

Thanks a lot for directing to the link.. It did the job perfectly..

Convert the cell array to a row vector, and then try. It should work

cell2mat(output1')
