You have probably either hit a Clatrix bug or have some kind of version mismatch with core.matrix - could you file an issue with the exact version numbers you are using and code to reproduce: https://github.com/tel/clatrix/issues ?
Note that "*" in clojure.core.matrix.operators is for element-wise multiplication (multiply corresponding elements in an array), not inner-product (matrix multiplication). You want "mmul" or "inner-product" for traditional style matrix multiplication.
