Unable to display symbolic expression

I have a small .mat file attached (29kB), which contains a struct of symbolic expressions. If I want to print or substitute the symbolic expressions, MATLAB freezes. This happens e.g. with Test.t1 My first thought was, that the expressions are to complex/long to display, but how can that be if the .mat is so small?

Try to display the first element of Test.t1
Test.t1(1)
Output truncated. Text exceeds maximum line length of 25 000 characters for Command Window display
The expression is too big in length (not in memory) to be displayed by Matlab

You may be able to SIMPLIFY the symbolic command or use VPA to approximate rational numbers using a small number of decimal places in order to reduce the length of the symbolic expression.

You could try this:
tfile = tempname;
feval(symengine, 'write','Text', tfile, Test.t1(1));
t11string = fileread(tfile);
Now you can examine t11string using any convenient method. But it may be large...
