Why do I receive matrix dimensions errors when... Learn more about MATLAB (a) When entering a vector or a number, MATLAB automatically echoes what has been entered. This echoing can be suppressed by appending a semicolon to the line. For example, type z = [-1 2 3]; and MATLAB responds with a new line awaiting a new command. To see the contents of the vector z just type z and MATLAB responds with z=-1 2 3Vector or matrix dimensions, specified as a vector of integers. nrow is the number of rows, and ncol is the number of columns. As a shortcut, you can create a square symbolic matrix variable by specifying only one integer. For example, X = symmatrix('X',3) creates a square 3-by-3 symbolic matrix variable. at the beginning of a line, which is the way the reader would see it the screen in the MATLAB workspace.

Accepted Answer: Stephan. I am trying to print code to look like the following, inserting variables in between text This displays the contents of the array as a row vector though, changing the original shape of the matrix.The result is a column vector of the elements in A that are less than 9. Since B is a logical matrix, this operation is called logical indexing. In this case, the logical array being used as an index is the same size as the other array, but this is not a requirement. For more information, see Array Indexing.check = mod (G_sys*H_sys',2); % to see if orthogonal.

And what the result check must be to see if it is orthogonal or not ?However, one easy way you can see that your vector is not in the column space of that specific matrix is to notice that the columns are scalar multiples of each other (multiply the first by − 2 ), so the column space is a line in R 2 with slope − 2 passing through the origin, and the point ( 1, 2) is very clearly not on this line. ShareSome useful functions to check sizes and number of elements are numel(), size(), and length(). 3. Subscript indices must either be real positive integers or logicals. The most common reason this message arises is that people come to MATLAB from other programming languages and can't get used to the fact that MATLAB indexing begins at 1.This instruction set explains how to solve a matrix equation and perform statistical analysis on a matrix in MATLAB.

The matrix is created in column-major order. Therefore, just using reshape by itself will place the elements in the columns. Since you desire the elements to be populated by rows, a trick is to simply transpose the result.I want to construct a new matrix Q that states if P_1(1:2) belongs to a row in N, then it should give a 1, otherwise 0.
