I am attempting to plot the Gas Turbine efficiency as a function of the temperature ratio:
Tr=1:10<3;
n=1-1/Tr;
figure
plot(Tr,n)
When attempting to plot i get the following error:
Error in ==> test at 5
n=1.-1/Tr;
??? Error using ==> mrdivide
Matrix dimensions must agree.
Any help would be appreciated, thanks in advance.

I do not know what you intend with this assignment:
Tr=1:10<3;
since it creates this logical array:
Tr =
1 1 0 0 0 0 0 0 0 0
Which is likely not what you want, because it creates with this assignment:
n=1-1./Tr;
this result for ‘n’:
n =
0 0 -Inf -Inf -Inf -Inf -Inf -Inf -Inf -Inf
