<p> Leader: James MATLAB If Statements Course: ChE 160 Supplemental Instruction Instructor: Heinen/ Stiehl/ Brenza Iowa State University</p><p>Where: Look in the Matlab primer for any of this information</p><p>Discussion The first element when understanding how to program. If statements are used so extensively, that mastering them early will save you an incredible amount of headache.</p><p>Concept Questions How do you end an If statement? What is the difference between Else and Elseif?</p><p>Review For the following: What is the value for z when input = 18? What are the values for a, b and c? What is the value for z when input = 190? a=2; b = 22; c = 199; if a < 4 z = input('Enter a number: '); c=17; if z == 40 elseif b~=c z=z*4 c=26 elseif z < 20 end z=z/3 else z=176 end What is the value for z when: z=4? z=60? What are the errors in this code? z= 120? j = 16; k = 44e-6; z = InputBox ("Enter a number") if k = 4 If z > 110 Then j = 16 z = z - 4 else q ~= 4 ElseIf z < 40 Then j = 2 z = z * 6 else k => 16 Else j =1 z = 176 end End If</p><p>Exam Prep Just screw around with the IF statements. The best way to understand is to just try using them over and over again.</p><p>1060 Hixson-Lied Student Success Center v 515-294-6624 v [email protected] v http://www.si.iastate.edu</p>
