As long as size(r,2 ) is the number of columns of matrix r, size of pp will be equal to size of r. dim2: The number of columns. A matrix can store data of a single basic type (numeric, logical, character, etc.). Here, Create a square matrix of zeros of even order Mimic of the MatLab function of a similar name. You will learn to create, modify, and access R matrix components. To create a two-dimensional array of zeros, pass the shape i.e., number of rows and columns as the value to shape parameter.. In stufield/stuRpkg: The Stu R Package. As long as size(r,2 ) is the number of columns of matrix r, size of pp will be equal to size of r. Details. So code pp=zeros(1,size(r,2)); will create matrix pp with 1 row and size(r,2) columns. ones Return a new array setting values to one.
