ones — Matrix of ones


\begin{rail} Ones : 'ones' '(' (( Scalar ',' Scalar ) \vert ( Matrix )) ')' ; \end{rail}
ones creates a matrix with each element set to 1. The arguments specify the dimensions of the matrix to be created. If the argument is a matrix, the matrix must have two elements, with the first argument specifying the number of rows, and the second argument specifying the number of columns. This is the same format as the output of the size function. If the arguments are two scalars, then the first argument is the number of rows, and the second argument is the number of columns.
