The KK-compactification of D=10 super Yang-Mills theory all the way to the point yields a theory whose fields are simply elements of the gauge Lie algebra $\mathfrak{g}$, hence matrices for a matrix Lie algebra. This physics is called the IKKT matrix model.
Alternatively this model can be motivated from a certain regularization of the worldsheet action functional of the superstring. This is how it was originally obtained in (IKKT 96).
It has been argued that for $\mathfrak{g} = \mathfrak{su}(N)$ the special unitary Lie algebra and in the large N limit, this model captures aspects of non-perturbative type IIB string theory (which would be F-theory, see also at M-theory). Therefore this is also called the IIB matrix model (in contrast to the BFSS matrix model in type IIA string theory).
Several authors have explored the possibility to lift the derivation of the IKKT model from the superstring to the M2-brane. See at membrane matrix model for more on this.
In (Kim-Nishimura-Tsuchiya 12) it is claimed that computer simulation of the IKKT matrix model, regarded as non-perturbative type IIB string theory, shows a spontaneous emerging spacetime of macroscopic dimension 3+1, with 6 microscopic dimensions. (A similar claim results from a very different argument: the Brandenberger-Vafa mechanism.)

There are claims that numerical computer simulations (as in lattice gauge theory, see the references there) show that the IKKT matrix model predicts a spontanously generated spacetime where exactly 3+1 dimensions become macroscopic (hence effectively predicts moduli stabilization in spintaneous KK-compactification of M-theory to $D = 3+1$ macroscopic dimensions ):
