Defined a variable in work space:
The variables defined in the script will become a part of the workspace:
>> clear
>> who
>> mysummfile
15
Your variables are:
i runsum vec
The Variables which are defined in the Command Window can be used in the script, but cannot be used in a function. For illustration, the vector vec could be defined in the Command Window (rather than in the script), but used in the script:
>> vec = 1:7;
vec
>> mysummfileii
>> runsum
runsum =
28
This, though, is very bad programming style. It is much better to pass the vector vec to the function.
It is possible, in a MATLAB and also in other languages, to have global variables which can be shared by functions. Though there are similar cases in which using global variables is efficient, it is normally regarded as the poor programming style.
Execute a exponential function program: Running the script will take up the menu as shown in the figure: Then, what happens will totally depend on which button(s) the
Subfunctions: Though, it is possible to have more than one function in a given M-file. For illustration, if one function calls the other, the first function would be the prima
readlenwid function: function call: [length, width] = readlenwid; function header: function [l,w] = readlenwid In the function call, not any argument is passed; henc
calcrectarea subfunction: function call: area = calcrectarea(len,wid); function header: function area = calcrectarea(len, wid) In the function call, the two arg
Example of Gauss-jordan: For a 2×2 system, this would results and for a 3 × 3 system, Note that the resulting diagonal form does not involve the right-most col
Intersect function and setdiff function: The intersect function rather than returns all the values which can be found in both of the input argument vectors. >> intersect(v
Vector operations: As vectors are special cases of matrices, the matrix operations elaborated (addition, subtraction, multiplication, scalar multiplication, transpose) work on
Illustration of Sorting strings: To sort on the rows rather than second dimension should be specified. >> sort(words,2) ans = Hello Hdowy Hi Gbdeo
Example of Menu driven modular program: As an illustration of such a menu-driven program, we will write a program to discover the constant e. The constant e, known as the n
