A scalar can multiply a matrix of any size. 4 .* Array multiplication. A.*B is the element-by-element product of the arrays A and B. A and B must have the same size, unless one of them is a scalar. 5 / Slash or matrix right division. B/A is roughly the same as B*inv(A)...
If I insert a simple filter inline with this number output from the matrix multiply, I get an error of matrix multiply propagation error. Here's what works: I display dims on all signals, so no display means scalar. This doesn't work: ...
• Python — Cell arrays and character arrays must be of size 1-by-N and structure arrays must be scalar. There are no restrictions on numeric or logical arrays, other than that they must be rectangular, as in MATLAB. See Also compiler.build.cppSharedLibrary | compiler.build.javaPackage ...

Operator *, dot(), and multiply(): For array, '*' means element-wise multiplication, and the dot() function is used for matrix multiplication. For matrix, '*' means matrix multiplication, and the multiply() function is used for element-wise multiplication....
Thus mod(2*J,n) will (scalar) multiply the entire J array with 2, before reducing each element modulo n.MATLAB does include standard "for" and "while" loops, but using MATLAB's vectorized notation often produces code that is easier to read and faster to execute.Most commonly used ...
Then, you are attempting to multiply them together. For these 1xN arrays, this is equivalent to taking the dot or scalar product. However, the scalar product only works when the left operand is 1xN and the right is Nx1, so MATLAB produces an error message and suggests the dot-star ...
