How To Create Points In Siemens NX(Illustrated Expression)
This text shows how to obtain vectors in Matlab® and how to create vector variables in Matlab® codes. As its name implies, Matlab® generally works with the base of matrices. Also, vectors are matrices and you could do various matrice calculations with your created vector in Matlab®. Also, you could do mathematical calculations with Matlab® vectors and you could insert the Matlab® vector to mathematical calculations with other matrices, vectors, and individual variables. This is much easier in Matlab® coding compared with other software languages.

v = [1 0 0] d = [1; 2; 3] z = 1:.5:3 p = pi*[-4:2:4]/4
There are a bunch of vector examples in the Matlab® script above, we will talk about their working principles below.
>> v = [1 0 0] d = [1; 2; 3] z = 1:.5:3 p = pi*[-4:2:4]/4 v = 1 0 0 d = 1 2 3 z = 1.0000 1.5000 2.0000 2.5000 3.0000 p = -3.1416 -1.5708 0 1.5708 3.1416 >>
As you can see the v vector is very basic and shows how to create a vector in Matlab® in principle. d vector shows how to create column vectors in Matlab®. You could understand that if you put ‘;’ between vector numbers, this vector will be a column vector like d. The meaning of z vector, ve create the z vector starts with 1, ends with 3, and increment of each element in z vector is 0.5. You could type the first value, increment value, and end value to create a vector by putting ‘:’ between these values.
In p vector, we did a bunch of mathematical calculations by using a vector-like z. As you can see we multiplied an increment vector with pi and divided it with 4.
