How make coding for condition in MATLAB

Line 19 how to write the code for conditioning for sqrt(1-((PA/Ps)^0.2856)

so that (PA/Ps)^0.2856 is equal to "a" and the condition "a" must be less than 1

if "a" is more than 1 the value of "a" is change to 0.1

Answer 1

[dpb]

a=(PA/Ps)^0.2856;
if a>1, a=0.1; end

It would seem that's a pretty big discontinuity to introduce, however, by the choice of replacement value. You sure you don't want just

a=min(a,1);

which could be written as

a=min((PA/Ps)^0.2856,1.0);

Or, would it perhaps make more sense to move up in the logic and limit PA, maybe???
