Matrices: Extracting Rows and Columns in Mathcad Prime
This video shows how to use the Matrix Row Operator and the Matrix Column Operator of PTC Mathcad Prime.
The two operators are useful when you need to extract particular datasets from a larger data array, including through an Excel Component / READEXCEL.
Note that the starting index for all vectors and matrices is determined by the built-in variable ORIGIN. By default it is 0, but you can change this.
