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.
Interpolation and extrapolation: In most cases, it is desired to estimate values other than at the sampled data points. For illustration, we may want to estimate what the temp
Modular programs: In a modular program, the answer is broken down into modules, and each is executed as a function. The script is usually known as the main program. In orde
Illustration of gauss-jordan: Here's an illustration of performing such substitutions by using MATLAB >> a = [1 3 0; 2 1 3; 4 2 3] a = 1 3 0 2 1 3 4 2
Scaling: change a row by multiplying it by a non-zero scalar sri → ri For illustration, for the matrix:
I have a 400x2 vel.dat and 20x2 xy.dat file, how can i plot a streamslice graph on matlab with this two files.
Creating the structure Variables: Creating a structure variable can be accomplished by simply storing the values in fields by using assignment statements, or by using the stru
Function iscellstr - string function: The function iscellstr will return the logical true when a cell array is a cell array of all the strings, or logical false if not. >>
