Day Date: Saturday, 25-11-2017 Max. Marks: 70
Time: 02.30 PM to 05.00 PM
Instructions: Q.1 and Q.2 are compulsory.
Attempt any three questions from Q. 3 to 7.
All questions carry equal marks.
Q.1 Select the correct alternative: 08
Consider matrix B generated by the following expression
B ones eye which of the following is true
B 4 gives error
B 1
The value of is 1.
If C B then the value of is a complex number 2.0000
1.0000i
Which of the following determines the number of elements N of the
matrix
N elem(B) N prod(size(B))
N numel(B) Both b and c
The difference between a function and a script is
Only a function file can be run from the command line
Function variable names only have meaning within the function,
whereas script variables are available to other programs
Only script file can perform a series of commands.
Functions cannot save variable values.
The volume of a cylinder is Define as 3 and as the row
column 12]. Which of the following MATLAB expression is
correct for solving the volumes of cylinders with the above h values?

Being able to store a list of items in both a string and integer format
allows for intuitive programming and a user friendly interface. This is
made possible with the data type.
Enum String
Integer Cluster
A For loop in LabVIEW is different from While Loop because it runs for
a set number of iterations and does not require a The
number of iterations is set by the
Input Tunnel, Count Terminal
Conditional Terminal Count Terminal

Q.1 State true and false 06
Whose command displays a list of the variables currently in the
memory and their size together with information amount their bytes and
class.
Clear command Clears command windows, command history only.
A Refers to the elements in all the columns between rows m
and n of the matrix A.
Numeric controls are different from numeric indicators because they
have a white background and Increment/Decrement Buttons.
Shift Registers not conform to the Dataflow programming paradigm.
Strip chart mode should be used to show running data continuously
scrolling from left to right across the chart.

A worker is paid according to his hourly wage up to 40hours, and 50% more
for overtime. Write a program in a script file that calculates the pay to a
worker. The program asks the user to enter the number of hours and the
hourly wage. The program then displays the pay.
