How do you define a structure array?

I have a function that defines the following variables:

xmin = procPar.xmin;
tmin = procPar.tmin;
fmin = procPar.fmin;

I'm using this:

procPar.xmin = Dsifile.th{1}(37,1);
procPar.tmin = Dsifile.fh{1}(1,9);
procPar.fmin = 10;

but I'm getting an error that says "Dot indexing not supported for variables of this type"

What line are you getting the error?

Does it have to do with Dsifile? Does Dsifile have both th and fh as options?

I'm getting the error on line procPar.xmin = .....

xmin, tmin and fmin are defined in a function and the procPar.xmin ones are in my main script.

The file I'm using is Dsifile and it contains th and fh which are matrices containing time and distance data. fmin is a scalar not included in the Dsifile.

The structure looks like this:

Dsifile --> th --> xmin in row 37, column 1

fh --> tmin in row 1 column 9

What is size(procPar) ? What is class(procPar) ?

Possibly procPar already exists but is not a struct or table already.

Possibly Dsifile exists but is not a struct or table.
