![]() The third contribution is improving the proposed algorithm performance to its peak as discussed in the results section. Just as a vector with 4 elements is often described as a 4x1, so a 4x3 matrix could be described as a 4x3x1 (a slice of a 4x3xn block) or even a 4x3x1x1. It also copes with higher dimensioned matrices ('N-D arrays'), though there are a few surprises. The use of GPUs is the second contribution which reflects how strongly they fit for high performance tasks. Matlab supports the use of 1D vectors and 2D matrices. The rapid increase in GPUs performance coupled with the recent and continuous improvements in its programmability proved that GPUs are the right choice for computationally demanding tasks. The permute () function rearranges the dimensions of the specified array in the order specified by the vector dimorder. The algorithm is implemented on NVidia GeForce GTS 250 GPU (Graphics Processing Unit) containing 128 cores. Thus, the performance is improved as evident from the experimental results section. Both permutation levels exploit the fast on-chip memory bandwidth by transferring large amount of data and allowing for fine-grain SIMD (Single Instruction, Multiple Data) operations. MATLAB actually supports n-dimensional matrices, so you can see how this can. If you permute them then and then you show them with a plotting tool that. ![]() Matlab stores array dimensions and array number rows and columns. In the physical permutation, actual data elements are swapped. Im new to Matlab and having trouble figuring out how to plot a matrix. Its done like that because an image under MATLAB has Y/X dimensions as size. When AZ is a vector, multiple overlaid plots are created. The x-axis labels (temperature) are added to the plot. In the logical permutation, the address map is transposed for each data unit access. A two-dimensional curve can be rotated about an axis to form a solid. The suggested algorithm exploits the idea of mixing both logical and physical permutations together. This is the first contribution which is breaking the dimensions’ limitation of the base algorithm. The proposed algorithm has been tested on 3D, 4D, 5D, 6D and 7D data sets as a proof of concept. The algorithm is based on a novel 3D transpose algorithm that was published recently. Built with Sphinx using a theme provided by Read the Docs. This paper proposes an efficient in-place N-dimensional permutation algorithm.
