How to merge words in the cells to form a string

Hi

I stuck into a phase of my work where I am looking forward to merge the words staying in the cells to form a string. My scenerio is like following:

A=562833 x 1 cell containing these following cells:

As an example,

A{1,1} is of size {2x1 cell} contains words bihdai and majesti

A{2,1} is of size {5x1 cell} contains words model,love,take,time and ur

I am looking forward to merge the cells to form a string and final output would be like

A(1)=" bihdai majesti"

A(2)="model love take time ur"

When I am trying with cell2str or string() to solve this, I am getting following error as well:

Conversion from cell failed. Element 1 must be convertible to a string scalar.

I am attaching a samples of the variables

Would you please advise me how to solve this scenerio.

Thanks,

Could you attach the data as .mat file? What version are you using?

Hi. The size of the mat file is big. I attach few screenshots of the problem in my question. I am using r2019a version.

A={{"happy" "birdday"} {"I" "am" "a" "boy"} {"good" "boy"}};

S = strtrim(string(char(cellfun(@(c) sprintf('%s ',c{:}), A, 'unif', 0))))

Bruno Hi

thanks for your suggestion. But after trying your code, the following error is showing:

Brace indexing is not supported for variables of this type. I have uploaded few screenshots of the workspace. Might be it will help you to suggest me the path.

Error in calculateWord_Counts>@(c)sprintf('%s ',c{:}) (line 22)
    a_=strtrim(string(char(cellfun(@(c) sprintf('%s ',c{:}), A, 'unif', 0))));

The screen shot cannot desribe accurately your data structure/class.

Beside I never use the workspace so I don't know how to read it.

Answer 2

[madhan ravi]

cellfun(@(x) join(string(x)),A).'

Hi Madhan

Its showing this error after running your code:

a=cellfun(@(x) join(string(x)),A).';

Non-scalar in Uniform output, at index 1, output 1.
Set 'UniformOutput' to false.

Later I set this in to your code. But ultimately it did not convert it back in the strings. it converts data type of cell to string. (As the cell size is huge originally, I transpose your result to see inside the variables).

a_=a';

whereas I am looking to these outputs

a{1,1} will contain "bihdai majesti"

a{2,1} will contain "model love take time ur"

>> A={'Will';'you';'make like easier';'by';'clear for Godsake'}

A =

  5×1 cell array

    {'Will'             }
    {'you'              }
    {'make life easier' }
    {'by explaining'               }
    {'clearly for Godsake'}

>> join(string(A))

ans = 

    "Will you make life easier by explaining clearly for Godsake"

a_=a'; % then copy screen

followed by useless screen capture.

Please do

a__ = a(1:10);
save(' a__.mat','a__');

and attach the file a__.mat here for us to try.
