Using the ‘erfcinv’ function (part of core MATLAB) and writing it as an anonymous function:
z = @(p) -sqrt(2) * erfcinv(p*2);
where ‘p’ is the probability.
So:
zscore = z([0.025 0.5 0.975])
produces:
zscore =
-1.9600e+000 0.0000e+000 1.9600e+000

A bit late maybe, but I did end up putting it on the FEX, so here is the promised link: BlandAltmanPlot. Once Mathworks gets the example tab working again for github submission, you will even be able to see a nice doc.
