Loading table from object from .mat file

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

Do not LOAD directly into the workspace.

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

"why should I NOT load directly into the workspace?"

For most of the reasons listed here:

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
