What is Matlab and Why is it Used? Video Lecture - IT & Software

What is Matlab and why is it used?
Matlab may be what makes the grade for your
math classes.
So it is math software?
Like a calculator on the computer?
Matlab is best for light scientific computing.
It can do moderate data processing, though.
How does it compare to Mathematica and Maple?
Mathematica and Maple are used more for symbolic
solutions, turning a big equation into a smaller
one.
I know Matlab can be used to help me do my
calculus homework.
What else can it do?
You can use Matlab for intensive mathematical
computations, such as load calculations for
bridges designed in your engineering classes.
Can't you do stuff like that in Excel?
Matlab is far better than Excel for scientific
computing.
However, Excel wins when it comes to charting
and data presentation to the non-techie.
You haven't tried working with pivot tables
then.
Is it true you have to know programming to
use Matlab?
Matlab is easier to learn to program in than
other mathematical software like Mathematica.
It is also easier to debug Matlab code than
with the other tools.
I need a debugger in that bugger.
Another reason to use Matlab is because it
handles file inputs and outputs better than
Mathcad.
Great.
Then I save the massive data entry necessary
to do the calculations in the first place.
One of the only reasons Matlab is not used
more often is because Mathcad is cheaper.
Adding dollars and cents does not require
a major math program.
You have to hit the PHD level or be a math
major to need Mathematica in most cases.
For most users, Matlab is good enough.
What about Mathcad?
It is easier to use than Matlab, but it is
not as advanced.
You may find Mathcad falls apart on advanced
multivariate analyses or load calculations.
That's a load off my mind.
And Matlab's interface is easier to learn,
though Mathcad is theoretically the tool for
beginners.
Then I know to start with Matlab, as the first
major math software I should learn.
