Matlab length x : 1
Web1. ; 1. 1.] As a result, if A is a scalar, then Matlab will return a A*A matrix of ones but in Scilab you get a 1 (just because a scalar is a 1*1 matrix), so use ones (A,A) to get the same matrix B. If A is a vector, Scilab and Matlab give the same B. Finally, if A is a matrix, in Scilab, B will be a matrix having the same size as A whereas in ... Web第一句x1=x (:,1)和第二句x2=x (:,2)的语法结构是一样的。. 这里只以第一句为例。. 1. 首先是开头的x1=,这里的=号在matlab里面代表 赋值。. 赋值就是把等号右边的值复制给左边的变量。. 因此x1将会得到等号右边的东西。. 2. 等号右边是x (:,1)。. 这个x在之前就已经 ...

Web10 okt. 2015 · 1 Answer. x (1) = 0 and y (1) = 0 is very similar to initializing a list / array in Python where x and y are the list variables and the first position is 1. MATLAB starts indexing at 1, and not 0 like in Java and Python. The similar syntax in Java or Python is: x [0] = 0; y [0] = 0.
