Steps:
-Define values preceding the conical shock at isolator start (flowGamma, shockMach, shockAngle).
-Run script
-Plots will be created showing the resulting intake geometry as well as a plot showing calculated values against theta.
expCrv is used to toggle export of plotted curve to a .csv file (default enabled).
in some cases the ODE solver may continue solution beyond where cross-stream mach (CM) = 0, resulting in an extended curve plotted for geometry, to solve this adjust StopTol within eventFcn.
