Error in find Precision recall curve

2 views (last 30 days)
Hello
I am following https://www.mathworks.com/help/stats/perfcurve.html#bunsogv-XCrit to find PR curve. On x axis i need recall value and on y axis i want precision value. as per the syntax it would be
'XCrit','tpr'
'YCrit','ppv'
but is shows error
['XCrit','tpr','YCrit','ppv'] = perfcurve(Y,diffscore1,'HandGrip');
Error: Assigning the function output to this expression is not supported.
Please help me

Try without the quotations:
[XCrit,tpr,YCrit,ppv] = perfcurve(Y,diffscore1,'HandGrip');
In general quotations are used to specify strings (ie. names), which are not necessary for variable names.
