-/** GLES Compute kernel to perform reshaping on the weights used by convolution and locally connected layer
- *
- * Rearranges each 3-dimensional kernel to a single row leading to a matrix with linearized kernels.
- * In combination with the @ref GCIm2ColKernel can transform a convolution to a matrix multiplication.
- *
- * For example assuming a 3D weight kernel of 3x3 dimensions and depth of 2 we have:
- * @f[
- * \left( \begin{array}{ccc}
- * a000 & a001 & a002 \\

- * a120 & a121 & a122 \\
