#MATRIX TO CELL ARRAY MATLAB CODE#
This poses some great challenges when we want to write a general purpose code to retrieve sparse matrices based on the topological structures. The number of indices stored in each element is of variable lengths. I also have a logical array the length of p x 1. As it requires a polytopal data structure, the biggest difference with traditional finite element is: matlab - Select specific pages of 3D matrix with logic array - Stack Overflow Select specific pages of 3D matrix with logic array Ask Question Asked today Modified today Viewed 5 times 0 I have a 3D matrix n x m x p where p represents 1400 daily 2D data arrays. Recently I am learning to code “virtual element method” for Long Chen’s $i$FEM. the cell to matrix first then coverting the matrix to string array Theme Copy. this might mean keeping all of the arrays in one cell array: Theme. Operates in 4k by 4k matrices hundreds even thousands of times faster than direct implementations in compiled languages like C/C++ and Java. More Answers (3) Convert to cell array of character vectors - MATLAB. In MATLAB, the matrix is created by assigning the array elements that are delimited. Nevertheless, MATLAB is highly optimized in vectorized array and matrix operations using the LAPACK/BLAS backend, and as an interpreted/scripting language, MATLAB
concatenated in a simple matrix In such a case, the results need to be grouped in a cell array. Looping through a large array is usually a nightmare, even more so if we add if/then within, and/or for sparse matrices. 1001 tips to speed up MATLAB programs Yair M. If I want to access the data of each of the cells but just (2:60,1). Element-wise matrix vector multiplicationĪs is known, MATLAB is notoriously slow in executing for loops. I have a cell array of 1x10 where each of the 10 arrays are matrices of 80x31.Vectorization tricks for cell arrays in MATLAB
