==== 1. MATLAB Basic & Variables ====
  * Powerpoint: {{ :matlab_training:matlab_basicvariable01.pptx |}}
  * Random Function Demo : {{ :matlab_training:rand_func_demo.m |}}

=== Creating Variables ===
  * Create a variable called //visual_intensity// and make it equal to 92. Ensure that the assignment result is not shown on the screen. 
++++   Solution | 
<code matlab>
visual_intensity = 92; % The semicolon prevents displaying the result after assignment 
% Note that "%" sign indicates a start of a comment
</code>
++++

  * Create a variable called //simple_text// and assign it value of "A simple text but in Matlab". 
++++   Solution | 
<code matlab>
simple_text = "A simple text but in Matlab";
% Always a good idea to choose clear names for variables. As your code grows larger, those clear names help to remind the logic and context of the code.  
</code>
++++

=== Using and Displaying Variables ===
  * Create two variables called //num_words// and //num_sentences// and assign them values of 6 and 10, respectively. Compute a new variable //long_paragraph// as a multiple of //num_words// and //num_sentences//. Ensure that none of the variable assignments is outputted to the screen.
++++   Solution | 
<code matlab>
num_words = 6;
num_sentences = 10; 
long_paragraph = num_words * num_sentences; 
</code>
++++

  * Display values of //num_words// and //num_sentences// on the screen. 
++++   Solution 1| 
<code matlab>
num_words
num_sentences
% Because no semicolon was placed at the end of variable name, Matlab displays the value of that variable. 
</code>
++++

++++   Solution 2| 
<code matlab>
disp(num_words);
disp(num_sentences);
% disp is a built-in function and is a short version of the word display. This function is used to show variable values on the screen. 
% When you write a long code, it is a good practice to use disp function to print out results because you can later easily search and find in your code lines where you display final or intermediate results. Of course you will type a bit more, but it will save you time in longer run. 
</code>
++++

  * Create two variables called //probability_1// and //probability_2// and assign them values of 0.1 and 0.01, respectively. Compute a new variable //odds// by dividing probability_1 by probability_2. Display //odds// on the screen by ensuring there is semicolon at the end of the line where you display that result. 
++++   Solution | 
<code matlab>
probability_1 = 0.1;
probability_2 = 0.01;
odds = probability_1 / probability_2;
disp(odds); 
% 
</code>
++++

  * List all the variables that were generated during current session. How many did you get?  
++++   Solution | 
<code matlab>
who;
% You will get back list of all variables. There should be if you completed all assignments so far. 
% However, if you completed it your own way, you may get different result. Here is what I got: 
% long_paragraph     num_sentences   num_words         odds              probability_1     
% probability_2     simple_text       visual_intensity 
</code>
++++

  * Delete variable //probability_1//. 
++++   Solution | 
<code matlab>
clear probability_1; 
who;
% probability_1 is now missing from the list of in-memory variable. 
% You may notice that function clear
% You will get back list of all variables. There should be if you completed all assignments so far. 
% However, if you completed it your own way, you may get different result. Here is what I got: 
% long_paragraph     num_sentences   num_words         odds              probability_1     
% probability_2     simple_text       visual_intensity 
</code>
++++


  * Delete all variable and check that there are none left in the memory. 
++++   Solution | 
<code matlab>
clear all
who
% The command will return empty result because we just deleted all variables. 
% You may want to do this to clear up memory, but be careful that you can recompute everything 
% and ensure that you wouldn't lose the results permanently.
