This document provides instructions for Assignment #1 for a Structured Computer Programming course. It includes questions asking the student to run MATLAB code to store and display variables, use semicolons, look up MATLAB help for functions, and compute mathematical expressions in MATLAB. The student is asked to start MATLAB, explain the effect of semicolons, look up help for various functions, and use MATLAB to evaluate mathematical expressions provided.
![Q1) In MATLAB command window, type the following:
>> x = 2.5
>> y = 2.5;
>> A = [ 1 3 5 7]
>> B = [ 2; 4; 6; 8]
>> M = [ 1 3 5 7; 2 4 6 8]
What is the effect of the semicolon?
Q2) Write the suitable MATLAB help command to find out how to use the following symbols and functions in MATLAB:
Mathematical operation
Matlab help command
√푎
×
푎푏
sin−1(푥)
|푦|
Hint: help is used when you know the Matlab function and lookfor is used when you don’t know the Matlab function for the given operation.
For example: help sin
lookfor cosine x=2.5 store and display y = 2.5; store but don't display A = [ 1 3 5 7] store and display B = [ 2; 4; 6; 8] store but don't display M = [ 1 3 5 7; 2 4 6 8]store but don't display
lookfor power
lookfor multiply
