I just think that, in the context of some matrix operations ( eachrow in the link above), some methods would make more sense to return a matrix with some unitary dimensions instead following the pattern of always dropping unitary dimensions from methods returns. Now, I want to arrange them for one matrix. Hello everyone, I would like to construct a three-dimensional 3x3xL matrix from a series of one-dimensional vectors. I describe each image with a vector have to size is 8400 x 1. I think it is reasonable that exist a convention that a vector is always assumed to be a column (in the case we need to decide to treat it as a row or as a column) but at the same time there is an specific type to represent a column of an N-dimensional array that is different from the just-a-single-dimension-aware-vector. Hi everyone, I read a database image, it includes many images. For example, create a single row of four numeric elements. A single row of data has spaces or commas in between the elements, and a semicolon separates the rows. Now let's add 2 to each element of our vector, a, and store the result in a new vector. If you have a specific set of data, you can arrange the elements in a matrix using square brackets. First, let's create a simple vector with 9 elements called a. Creating a matrix is as easy as making a vector, using semicolons ( ) to separate the rows of a matrix. This example shows basic techniques and functions for working with matrices in the MATLAB language. To create a GPU array with underlying type datatype, specify the underlying type as an additional argument before typename. ![]() You can specify typename as gpuArray.If you specify typename as gpuArray, the default underlying type of the array is double. I will probably work on such enhancement next week. plot (b, ) axis ( 0 10 0 10) One area in which MATLAB excels is matrix computation. This MATLAB function returns the scalar 0. The best course of action seemed to give a better error message. A very useful tool offered by Matlab is elementwise multiplication and division. ![]() I was confused because I do not make much use of matrices but this somewhat did not align with I had seen in many discussion about Julia. 1.5 Elementwise multiplication, division and powers. Today, one of my laboratory colleagues has said to me he used Julia to make a small program, and while he overall liked the language he found the inconsistency between row and column major to have made him lost some sanity and wasted considerable development time. I have incentivized the use of Julia in my laboratory. `eachrow` over Array does not return rows, why? General Usage
