Program the for loop: Interpolate the data values as desired6:45
Learn to program a MATLAB/Simulink automation from scratch to use a for loop that interpolates data values by indexing table columns and retains previous values for intermediate samples.

Verify interpolated data values9:13

Requirements

a) No prior MATLAB experience mandatory. But basic SIMULINK modeling knowledge would be useful to understand the SIMULINK integration portion of the course.
b) No prior programming experience mandatory
c) You don’t need to have a MATLAB installation to take this course. But if you want to try out programming duringthe lecture you could download and use a trial version from the Mathworks website

Description

The course endeavors to show you, especially if you are a beginner, the coding process one can take to start developing a full-fledged GUI-based automation in MATLAB.

You are walked through each line of code as it is typed starting from the first line of code and as you progress through the lectures build up to a working automation program.

There are no written code comments or slides for the course.

Each line of code is explained as it is typed- in the form of a live coding session.

Who this course is for:

a) A beginner who wants to learn how MATLAB coding is done line by line for creating an automation
b) Professionals who are looking to fine tune their automation programming skills
