pwelch produces an estimate of the power spectral density, so what do you mean by 95%. I think you need to clarify 95% of what?

% Define the value we're looking for in our data, callled "theCurve".
threshold = 0.95 * max(theCurve); % or whatever you want.
% Find where this happens the first time.
theIndex = find(yourCurve > threshold, 1, 'first');
