Programming for Engineers (MATLAB)

Laboratory 4 - Formatted Output

Objectives: Demonstrate ability to produce a specified table of output. Demonstrate ability to convert a flowchart into a working MATLAB script file.

Exercise A

Data for several moons orbiting several different planets in our solar system is stored in the file L:\engr1120\MATLABCraveMmoons.mat Use the formulas from Laboratory #3 to evaluate the lunar characteristics for all moons in the data file. Assume that all of the units are consistent with those from Laboratory #3. NOTE that the equations may need to be modified slightly to accommodate different vector variables, if applicable. Also, modify the output so that a table is produced using the exact format defined below, there are 5 spaces between columns.

Exercise B

The flowchart on the following page describes a program that will begin by defining a vector of temperature values, given in Fahrenheit. The program then converts these temperatures into the other units commonly used for temperature: Celsius, Kelvin, and Rankine. The output from this program is to be a table showing the input temperature values and the corresponding converted temperature values, in columns.

You are to convert this flowchart into a MATLAB script M-file. The output table is to be properly labeled and have values that are appropriately aligned.

Test your program with various types of temperature vectors. For example, try using:

• one scalar input value

• a row vector of evenly spaced values (using the colon operator)

• a row vector of evenly spaced values (using the linspace function)

• a row vector of random values

• a column vector of random values (what would need to be changed in your script file?)

SUBMIT: Turn in a copy of the script file and a copy of the example output for Exercise B only. For the example output you are to use at least 5 temperature values that include 0, 32, & 212°F.
