Algorithm (Workflow)

This function, PLtransP, is designed to translate a list of points in a 2D space by a given translation vector. It is part of the SolidGeometry library and was introduced in version 1.1.

Input Parameters

• PL: A point list represented as an nx2 matrix, where n is the number of points. Each row corresponds to a point with its x and y coordinates.
• p: A translation vector represented as a 1x2 array. It contains the translation values for the x and y coordinates.

Output Results

• PL: The translated point list, which is the original list of points shifted by the translation vector p.

Algorithm Steps

1. The translation vector p is explicitly defined as a 1x2 array to ensure it has the correct dimensions.
2. The function uses the repmat function to replicate the translation vector p to match the number of points in PL. This creates a matrix of the same size as PL where each row is the translation vector.
3. The original point list PL is then added to this replicated matrix, effectively translating each point by the vector p.
4. If the function is called without an output argument, it automatically plots the translated points using the PLplot function. The view is set to a top-down perspective with view(0,90), and the plot is configured with equal axis scaling, grid lines, and axis visibility.
