How to read file .txt?

I have file .txt contains

1 2
2 3

I want to read the file and put each value 12 , 23 in a cell array

How can I do that

Please help me.

Thanks

Are the inputs actually separate in the file as shown and you really want them combined as numeric?

Why use a cell array for numeric values?

[Mira le]

I work with cell array the output like that

SI { 1 2 , 2 3}

SI{1}

1 2

SI{2}

2 3

You haven't answered dpb question. The simplest way to clarify what your input file actually looks like is to attach an example.

Also, please explain why you want the result as a cell array when using a matrix would make everything simpler.

SO how do we make it with matrix?

[Adam Danz]

@Mira le , please take a moment to think about the questions that dpb and Guillaume have asked. They are important.

Do you want this

{12, 23}

or this

{[1,2],[2,3]}

or something else?

If the answer is something else, show us exactly what you're looking for.

[Mira le]

I mean {[1,2],[2,3]}

If i want to put then in s for example like that

s={[1,2],[2,3]}

s =

1×2 cell array

[1×2 double] [1×2 double]

>> s{1}

ans =

1 2

>> s{2}

ans =

2 3

Assuming your text file is named myTextFile.txt and contains only that matrix,

A = readmatrix('myTextFile.txt'); % for Matlab >= 2019a
%A = dlmread('myTextFile.txt');   % for matlab < r2019a
B= mat2cell(A,[1,1],2).';      % If you want to split the matrix by rows
B= mat2cell(A.',[1,1],2).';    % If you want to split the matrix by columns

In your example it's unclear whether your splitting the matrix by rows or by columns since both result in the same output. Use the 2nd line above to split by rows and the 3rd line to split by columns. Both produce a 1x2 cell containing two 1x2 vectors.

[update]

This version below is more generalizeable in case the size of your matrix changes.

B = mat2cell(A,ones(size(A,1),1),size(A,2)).';    %by row....
B = mat2cell(A.',ones(size(A,2),1),size(A,1)).';  %by column...

Undefined function or variable 'readmatrix'.

[Adam Danz]

When you create a question in this forum, it's important to fill in the version of Matlab you're using. readmatrix() was released in r2019a. Apparently you're using an earlier version.

Use this line instead.

A = dlmread('myTextFile.txt')

[Mira le]

I use 2017a version matlab

[Adam Danz]

dlmread should work for you, then. I'll add your release number to the question details on the right.

That works for me too, thanks
