alternative to groupcounts function

I have made a script which I used groupcounts() function.

The pc where the script is running is previous to 2019. So that function is not recognized. I have tried to copy the function in the path but I get this error

{Undefined variable "matlab" or class "matlab.internal.math.parseGroupVars".

Error in groupcounts (line 105)
    [groupingData,groupVars] =
    matlab.internal.math.parseGroupVars(T,tableFlag,'groupcounts');
    
    

is there other function that provide the same outputs but work in previous versions than 2019?

I found this way. I hope someone can provide nicer way.

Original:

[xx,yy] = groupcounts(temp); 

Alternative:

[xx0,yy] = findgroups(temp);
[xx,~] = histc(xx0,unique(xx0));

[xx,yy] = groupcounts(temp);
