In Matlab I have integer array a=[1 2 3]. I need to convert them into one string, separated by ',':
c = '1,2,3'
If somehow I can have a string array b=['1' '2' '3'], then I can use
c = strjoin(b, ',')
to achieve the goal.
So my question is: How to convert integer array a=[1 2 3] into a string array b=['1' '2' '3']?
The int2str() is not working. It will give out
'1 2 3'
and it is not a "string array", so the strjoin can not apply to it to achieve '1,2,3'
You can simply use sprintf():
a = 1:3;
c = sprintf('%d,',a);
c = c(1:end-1);
There's a function in the file exchange called vec2str that'll do this.
You'll need to set the encloseFlag parameter to 0 to remove the square brackets. Example:
a = [1 2 3];
b = vec2str(a,[],[],0);
Inside b you'll have:
b =
'1,2,3'
I found one solution myself:
after getting the string (not array), split it:
b = int2str(); %b='1 2 3'
c = strsplit(b); %c='1' '2' '3'
Then I can get the result c=strjoin(c, ',') as I wanted.
You can use:
c = regexprep(num2str(a), '\s*', ',');
