Error in Matlab R2018a when use the functions 'calcDislocationDensities' and 'calcDislocationDensities'.

[pablobruno1]

Hello everyone,
I hereby would like to ask your help.
I've tried to use both functions 'calcDislocationDensities' and 'calcDislocationDensities' in Matlab R2018a together with Mtex version 5.4 and an error appears for me, for examples by saying: 'Undefined function or variable 'calcDislocationDensities'.
So, does this problem a problem with the Matlab version? or how could I solve this problem?

Best regards,
Pablo Leão

Hi,
mtex does not have a function called calcDislocationDensities. Maybe you need to explain a little more where you came along this?
There was a typo in the help for fitDislocationSystems but apart from it, I found no occurrence.

Cheers,

Dear Kilir,

Thanks for your reply.
Please look bellow the error message:

Hi,
the error message tells you that you need to have the Optimization Toolbox which supplies the function linprog which is required by fitDislocationSystems.
