Transforming 100x4 Char Array to 1x400 Char Array

Hello,

I have a char array with the dimensions of 100x4 and because it contains blank elements, in other words 4 charactered space ' ', I want to merge these elements and delete these 4 charactered blank elements. How can I do it? Thank you.

If you want to remove elements, this will change the number of elements, so any column vector will not have 400 elements.

It sounds like you should be using a cellstr (a cell array with char vectors) or the string data type.

That is what I want sir, i will remove them because it does not contains any information.

You have varities of functions to achieve this.

Try:

str = str(find(~isspace(str))) ; % where str is your string 

[tinkyminky93]

Now it shows

{0x0 double} {0x0 double}

{0x0 double} {0x0 double}

{'00'} {'00'}

any methods to remove 0x0 doubles? I need hex 00 00 values but not empty 0 elements :)

Once you have a cell array it's relatively easy to remove the empty elements:

str={[],[],[],[],'00','00'}

str = 1×6 cell array
    {0×0 double}    {0×0 double}    {0×0 double}    {0×0 double}    {'00'}    {'00'}

str(cellfun('isempty',str))=[]

str = 1×2 cell array
    {'00'}    {'00'}

Great! You can write it to answer section so that I can accept your answer. Now I have 32x1 cell which have 2x1 elements in every row. How can I merge them like 1x1? For example

0E

F9

to

'0EF9'

I don't understand your source data. With a 2x6 char array as an input, you don't get the cell array output with the code KSSV posted. So I can't post the full processing.

Regarding the merging:

str={'0E';'F9'}

str = 2×1 cell array
    {'0E'}
    {'F9'}

[str{:}]

ans = '0EF9'

@tinkyminky93 why don't you attch your data, so that we can have a look and help you.
