Accepted Answer. Set the ‘Position’ property on the current figure (gcf). Specify the position as a vector of the form “ [x0 y0 width height]”, where “x0” and “y0” define the distance from the lower-left corner of the screen to the lower-left corner of the figure. By default, the position is in pixels.
If A is a multidimensional array, then vecnorm returns the norm along the first array dimension whose size does not equal 1. N = vecnorm (A,p) calculates the generalized vector p-norm. N = vecnorm (A,p,dim) operates along dimension dim. The size of this dimension reduces to 1 while the sizes of all other dimensions remain the same. May 17, 2015 · The Matlab language does not support the syntax size(A)([2,3]) like some other languages do, so a call to subsref is the most direct way. However, I have added a simpler version that avoids a direct call to subsref if it is more to your liking. For limitations related to variable-size data, see Variable-Sizing Restrictions for Code Generation of Toolbox Functions (MATLAB Coder).

A vector is a one-dimensional array and a matrix is a two-dimensional array. We have already discussed vectors and matrices. In this chapter, we will discuss multidimensional arrays. However, before that, let us discuss some special types of arrays. Special Arrays in MATLABWhen you use [] to automatically calculate a dimension size, the dimensions that you do explicitly specify must divide evenly into the number of elements in the input matrix, numel(A). Beyond the second dimension, the output, B, does not reflect trailing dimensions with a size of 1. For example, reshape(A,3,2,1,1) produces a 3-by-2 matrix.This MATLAB function concatenates the arrays A1,...,AN along dimension dim. A multidimensional array in MATLAB® is an array with more than two dimensions. In a matrix, the two dimensions are represented by rows and columns. Each element is defined by two subscripts, the row index and the column index. Multidimensional arrays are an extension of 2-D matrices and use additional subscripts for indexing.Find the number of dimensions in the vector. ndims (A) ans = 2 The result is 2 because the vector has a size of 1-by-5.

Change Figure Size. Create a default figure. f = figure; Get the location, width, and height of the figure. f.Position. ans = 680 558 560 420. This means that the figure window is positioned 680 pixels to the right and 558 pixels above the bottom left corner of the primary display, and is 560 pixels wide and 420 pixels tall. The trailing singleton is dropped by MATLAB even from the point of view of the MEX API. The docs for mxSetDimensions say as much: MATLAB® automatically removes any trailing singleton dimensions specified in the dims argument. For example, if ndim equals 5 and dims equals [4 1 7 1 1], the resulting array has the dimensions 4-by-1-by-7.Here the size of each dimension is assigned to a separate variable. [m,n,p] = size (rand (2,3,4)) m = 2 n = 3 p = 4. If X = ones (3,4,5), then.
