Hi,
%to display the ptr value, we need to provide a name value pair for spec, something like:
gagerr(y,{part, operator},'randomoperator',true,'spec',[1 2])
Following 'spec' you must give the lower and upper limit of the process as a two - element vector just like I have provided above as [ 1 2 ]. For the example given on the documentation page, I get output as:
Columns 1 through 5
{'Source' } {'Variance' } {'% Variance' } {'sigma' } {'5.15*sigma' }
{'Gage R&R' } {[ 0.971542729463783]} {[ 99.2652690112843]} {[ 0.985668671239876]} {[ 5.07619365688536]}
{' Repeatability' } {[ 0.953483068176294]} {[ 97.4200623295928]} {[ 0.976464575996638]} {[ 5.02879256638268]}

{0×0 char }
Number of distinct categories (NDC):0
% of Gage R&R of total variations (PRR): 99.63
Precision-to-tolerance Ratio (PTR): 5.08
Note: The last column of the above table does not have to sum to 100%
I hope this clears your confusion regarding the syntax.
