Deleting Empty Rows in Cell Array

Hello,

I have a cell array like

' '

' '

'1231231'

' '

' '

'1231231'

' '

I want to delete this blank elements and transform this cell array from 7x1 to 2x1. How can I do it? Is there any methods to solve this problem without cellfun or etc.? Thank you.

If the data is in a cell array, mostly likely cellfun() is needed, unless you use for-loop.

strtrim() or strip() can remove the white spaces.

b={'             '
    '             '
    '1231231'
    '             '
    '             '
    '1231231'
    '             '};
c=strip(b);
index=cellfun(@isempty,c);
d=b(~index)

d = 2×1 cell array
    {'1231231'}
    {'1231231'}

First argument must be text, error using strip.

@tinkyminky: Does this mean, that your cell array does not contains CHAR vectors? Then the question is misleading. Please post some code, which creates your input data.

[tinkyminky93]

Yes it is. It does not contain anything. It is just created because of the for loop and there is no data inside of it.

@tinkyminky93: I do not understand, what you want to say. What does not contain anything? Which loop? What is the meaning of the ' ' blocks in your question?

If tzhese blocks are empty matrices instead of char vectors containing spaces, simple omit the strip command:

c = c(~cellfun('isempty',c))

Actually i am scanning all the text file with for loop and if it contains the data that I want, I am taking these values and deleting rest. Thats where for loop comes from.By the way my array is char array for now, is there any other method?

@Fangjun Jiang sir I applied your suggestion and it seems like that is what I want. But I have a problem. My data becomes 32x1 cell and every element is 2x1 cell. What I want is 32x1 and every element is 1x2. How can I do it?

Provide some example data that others can use directly in MATLAB to help you. For example

' '

'1231231'

can not be used directly in MATLAB, while

a={' '

'1231231'}

can so others can use it to provide you with example code.
