About Exercise 4
Vectors and matrices, also called arrays, are used in PTC Mathcad for matrix calculations and for storing data. Several methods to insert and to edit matrices are available. You can start with a 1–element array, and then build the array by adding rows and columns, or you can use a matrix template on the Matrices/Tables tab. You can also use index notation to evaluate or define individual array elements. After completing this exercise, you will be able to perform the following tasks:
Insert and define arrays
Perform matrix calculations
Use operators or functions to extract data from an array
