Origin Ver. and Service Release (Select Help-->About Origin): 2022
Operating System: win10

I have a xml file in which I read a string value that actually represents many vectors
string looks like this:
"0,19,126,163,29,0,0,0,0,0,
0,0,0,209,0,0,35,148,159,264,
468,66,421,706,639,506,399,716,604,382,
535,414,304,563,493,223,250,6,53,0,
0,0,81,0,0,0,0,0,0,0,
....
and so on"

I can put it into a vector<string> with GetTokens(), but then I need to further extract each element into separate vectors.
This is doable with a loop but this is way too slow (I have more than 20000 lines)

Is there any method that could speed things up ?
This string has the same structure than an ascii file, would it be possible to use ImportASCIIFile(), with a string instead of a file ?

Thanks

Hi,

In 2022b Beta version, we added a function SetByText() for matrixbase.

void st(string str="1,2,3\r\n2,3,4\r\n7,8,9\r\n")
	{
		matrix<int> mm;
		mm.SetByText(str);
		Worksheet wks = Project.ActiveLayer();
		mm.CopyTo(wks);//default will transpose
	}


People who is interested may try.
