How can I solve the following differential equation with MATRIX?
where T is the unknown:
P is known (I know P4, P5 and P6):
R^-1=G is known (I know all its terms):
C is known (I know all its terms):

Yes your system of ODEs are on the form (with singular mass-matrix, C) that ode23t and ode15s can handle, at least according to the help and documentation.

Start by looking at the odeexamples - that gui lets you run and inspect a good number of examples with different combinations of the ODE-integrators' capabilities. You can also look at the source code of them, which should illustrate how to write the code.
In this example you should save the first code-snippet to a .m-file with the name fcn_dTdt.m and then put the setup and ode15s call either in a script or on the command-line.
