I import a table object that I have stored in a .mat file (attachment) using:
ParaDat=load('ParameterDatabase.mat')
Then, I try to assign values to the different elements of that table, e.g.
A1=ParaDat.a1
but this line generates the error message: Unrecognized field name "a1"
Also, if I try to convert the imported struct to a table using:
Dat=struct2table(ParaDat)
A1=Dat.a1
but I wtill see the same error message. How can I address the different variables of the imported table?

Your MAT file contains one table named PARATABLE:
S = load('ParameterDatabase.mat')
S = struct with fields:
ParaTable: [1x10 table]
T = S.ParaTable
T = 1x10 table
Sample a1 b1 c1 a2 b2 c2 a3 b3 c3 ___________________ _______ ______ __________ ______ _______ _________ _______ _______ __________ {'BBX2_Isopentane'} -1.9324 9.6297 -0.0084416 4.8199 -8.5584 0.0088016 0.66304 -1.7523 -0.0019275
T.a1
ans = -1.9324
Do not LOAD directly into the workspace.

OK, thanks, Stephen, but why should I NOT load directly into the workspace?

If the table object in that .mat file is called MyTable, then after ParaDat=load('ParameterDatabase.mat'), you can access it by
ParaDat.MyTable
If you run load('ParameterDatabase.mat'), then you can access that table directly
MyTable
