How to solve the error in using multiple solution number for data evaluation?

Dear all,

I tested the example for using mapmatrix in the LiveLink™ for MATLAB® User’s Guide. The matlab code is listed as follows

model = mphopen('modeltutorialllmatlab'); std = model.study.create('std1'); time = std.feature.create('time', 'Transient'); time.set('tlist', 'range(0,1,25)'); std.run; str = mphmatrix(model,'sol1','out',{'K'},'initmethod','sol','initsol','sol1','solnum',15);

However, if another solution number is specified, an error will be found.

str = mphmatrix(model,'sol1','out',{'K'},'initmethod','sol','initsol','sol1','solnum',11);

The error imformation is:

Error using mphmatrix Cannot set the property 'solnum' to '11'. Allowed values are: 'auto' 'first' 'last' 'interp' 'manual' '1'

How to solve this problem? Thanks.
