convert number to string but keep it the same as it is

Hi,

I have a Matrix containing different time series and I gave them numbers (2000001, 2000002,2000003 etc.) and I would like to convert this numbers into a string. If I use int2Str I get some Kind of matlab representation of this number, but this is not what I am looking for. What I need is at the end a vector as follows:

A=['2000001','2000002','2000003', etc.]

how can I achieve this by a automatic command?

regards

In one line:

M = [2000001, 2000002,2000003];
S = strsplit(num2str(M));

produces:

S = 

      '2000001'    '2000002'    '2000003'

I get the error: Undefined function 'strsplit' for input arguments of type 'char'.

is it possible that strsplit is from a toolbox? i have matlab version 2012, is it possible that this version does not contain that function?

I didn’t see the semicolons that indicated you want them as a column vector of strings.

This works:

M = [2000001, 2000002, 2000003];
S = strsplit(num2str(M))'

and produces:

S = 

      '2000001'
      '2000002'
      '2000003'

If ‘M’ was initially either a row vector or a column vector, this works:

M = [2000001, 2000002, 2000003]';
S = strsplit(num2str(M(:)'))'

producing the same column vector as before.

Either num2str or int2str will work in this application.

strsplit (and strjoin) were introduced in version 2013a, if I recall.

[Star Strider]

I don’t remember when it arrived.

In its absence, this is as good as it gets:

S = cellstr(int2str(M(:)))

and produces:

S = 

      '2000001'
      '2000002'
      '2000003'

You can achieve that command using transformation from matrix to cells, if M is your matrix :

      M=magic(10);
      N=size(M);
      B=mat2cell(num2str(M(:)),ones(N(1)*N(2),1));
      B=reshape(B,N(1),N(2));

You can convert each number separetely in the for loop.

for i=1:numel(M)

out(:,i)=int2Str(M(i))

end

And you will have out - array of strings Code may have some errors - i didn't try to compile it

tis results in

222
000
000
000
000
000
123

but that is exactly what I whant to avoid
