The introduction of complex matrices to EJML is very recent and he best way to handle them is still undecided. The only way to manipulate complex matrices is using a procedural interface. The complex analog for each procedural class can be found for the complex case by adding "C" infront of it. Here are a few examples:

{| class="wikitable"
! Real !! Complex
|-
| CommonOps || CCommonOps
|-
| MatrixFeature || CMatrixFeatures
|-
| NormOps || CNormOps
|-
| RandomMatrices || CRandomMatrices
|-
| SpecializedOps || CSpecializedOps
|}

The complex analog of DenseMatrix64F is DenseMatrixC64F. The following functions provide different ways to convert one matrix type into the other.

{| class="wikitable"
! Function !! Description
|-
| CommonOps.convert() || Converts a real matrix into a complex matrix
|-
| CommonOps.stripReal() || Strips the real component and places it into a real matrix.
|-
| CommonOps.stripImaginary() || Strips the imaginary component and places it into a real matrix.
|-
| CommonOps.magnitude() || Computes the magnitude of each element and places it into a real matrix.
|}

There is also Complex64F which contains a single complex number. [[Example Complex Math]] does a good job covering how to manipulate those objects.

-The introduction of complex matrices to EJML is very recent and he best way to handle them is still undecided.  The only way to manipulate complex matrices is using a procedural interface.  The complex analog for each procedural class can be found for the complex case by adding "C" infront of it.  Here are a few examples:
+Most real operations in EJML have a complex analog.  For example, CommonOps_DDRM has the complex equivalent of CommonOps_ZDRM.  ZMatrixRMaj is the complex analog for DMatrixRMaj.  Floats are also support, e.g. FDRM -> CDRM.  See tutorial on [[Procedural|procedural interface]] for a table of suffixes.
