Question

Using octave, Write a script that prompts the user for a vector of multiple measurements of a cylinder’s radius. The script should then prompt the user for a vector of multiple measurements of a cylinder’s height. The volume v of a cylinder with radius r and height h is given by v = πr2h. The script should then calculate and print the volume obtained for each pair of trial measurements. The script should work for any number of trial measurements. Sample output: Enter a vector of radius data: [ 5.499 5.498 5.5 5.5 5.52 5.51 5.5 5.48 ] Enter a vector of height data: [ 11.1 11.12 11.09 11.11 11.11 11.1 11.08 11.11 ] The volume for each trial is: 1054.5 1056.0 1053.9 1055.8 1063.5 1058.7 1053.0 1048.2 Enter a vector of radius data: [ 10.1 9.9 10.05 ] Enter a vector of height data: [ 3.1 3.0 2.9 ] The volume for each trial is: 993.47 923.72 920.20. Also, use disp to print entire vectors of numbers.

Answer 1

Please find the solution below:

Solution:
Steps for the script are as follows:
Prompt and Read the radius vector from the user.
Prompt and Read the height vector from the user.
Calculate the volume as per the given formula.
Note that you need to use the .* for the vector multiplication.
Display the volume to the user.

Sample Octave Script:

%%%%%%%%%%%%%%%%%%%%%%%%%

% Sample script to calculate the volume vector

%%%%%%%%%%%%%%%%%%%%%%%%%
% read the input

rValues=input("vector of multiple measurements of Radius:","s")

% split the string delimited by space

r=cellfun("str2num",strsplit(rValues," "))

hValues=input("vector of multiple measurements of Height:","s")

% split the string delimited by space

h=cellfun("str2num",strsplit(hValues," "))

% Calculate volume as per v = πr2h

v=pi.*r.*r.*h

%Display the volume vector

disp(v);
