Hi I linked MATLAB with ModeFrontier. When I run the my code in MATLAB I get correct result but when using ModeFrontier I get the following error: Error: Unexpected MATLAB expression. "MATLAB:m missing operator" this my code where SP_MATLAB is a mex fortran file that is without any error when running in MATALB.
x=0;
L1 = L + x;
B1 = B + x;
T1 = T + x;
Z1 = Z + x;
EAR1 = EAR + x;
DIA1 = DIA + x;
RPM1 = RPM + x;
PDR1 = PDR + x;
% L=25.0;B=3.5;T=1.5;
% Z=5;EAR=0.5;DIA=1.75;RPM=250.0;PDR=0.83;
[RW,ETA]=SP_MATLAB(L1,B1,T1,Z1,EAR1,DIA1,RPM1,PDR1);

The error message does not contain the contents of the failing line - what a pitty. The problem might be in the calling sequence of the Matlab code, but the code itself looks strange also: What is "L", "B", "T" and "Z"? This cannot run without problems inside Matlab, except if these symbols are functions without inputs. The same for "EAR", "DIA", "RPM" and "PDR".

All L,B,T,Z,EAR,DIA,RPM,PDR are input variables that enter from ModeFrontier software. In it's help it has been told that "The script to be executed must not start with a clear (or with an equivalent) Matlab command. Otherwise, the variables defined in modeFRONTIER will be deleted from the Matlab environment." So I defined the variable 'x'. When I run the following code in MATALB without linking ModeFrontier I didn't get any error:
L1=25.0;B1=3.5;T1=1.5;
Z1=5;EAR1=0.5;DIA1=1.75;RPM1=250.0;PDR1=0.83;

Hi, I have the same error now, 4 years later. Did you solve the problem??

I just stopped using functions. If you work with normal .m matlab codes, it will work normally.

hello victor okay here is more details on my problem.
like the guy above I am coupling matlab code to modeFRONTIER. In the modeFORNTIER environment i input my matlab script and connect the necessary input and output variables to other components in modeFRONTIER. My matlab script takes in input variables from modeFRONTIER and runs a calculation that gives both scalar and matrix(vector) outputs back to modeFRONITER.
The script works fine when i run it in the matlab environment. However, when i run it through modeFRONTIER i get the error. After investigating (i.e. looking through the files generated by modeFRONTIER) i noticed that the scalar ouput variables are obtained by modeFRONTIER with no issues, but modeFRONTIER is having a problem obtained the matrix output variables.
Here is the code
format short g
actual_inj_law = load('inj10mm3.dat'); %injection law for 10mm^3 fuel quantity
time_law = actual_inj_law(:,1); %time of the injection law
fuel_law = actual_inj_law(:,2); %fuel flowrate of the injection law
act_inj_p = 1200*10^6; %actual fuel injection pressure
des_inj_p = 1200*10^6; %desired fuel injection pressure
total_fuel_quant = trapz(time_law,fuel_law); %old fuel quantity injected

If anyone ever sees this.
I had the same issue.
what solved it for me, is to make sure that if you use EXE files, put them in a folder that is in one of the folders that the PATH varible points to.
For some reason modeFrontier doesn't read exe files if they're not there.
Also, make sure you open modeFrontier as an Admin.
