Difference between function and scripts
Function commands don’t change the workplace, but script does
What do matrices need in MATLAB?
Square brackets
What would be the output?
What is X and Y?
What do commas and semi-colons do in matrices/vectors?
Commas/ spaces separate columns
semi-colons separate rows
What would be the input?
What would be the output?
What would be the input?
what is d = a(1,3);
(b,c)
where
b = position of row
c = position of column
Get value in first row, third column
Therefore d= 6
What is a(1,3) = 60;
Set value at first row and third column to 60
What is the output?
3 = rows
2 = columns
What is the output?
What is the output?
What do colons do?
creates loops similar to for-loops
What is the output?
Give the vector position definitions
What is the output?
What is the output?
What would this create?
1) 3 rows, 4 columns of zeroes
2) change values to 7, 8
3) change values to 5
Q1
Get values of 2nd to 4th row and 2nd column
Q2
Get values of 1st to 3rd row and all columns
Q4
Set values of 1st to 3rd row and 2nd column
What is
C = [a,b]
D = [a;b]
What is b’s output?
