Arithmetic operators in MATLAB - Step-by-Step Execution
Execution Sample
MATLAB
a = 5; b = 3; c = a + b; d = a * b;
This code adds and multiplies two numbers, storing results in variables.
Execution Table
| Step | Variable | Operation | Value | Explanation |
|---|---|---|---|---|
| 1 | a | Assign | 5 | Variable a is set to 5 |
| 2 | b | Assign | 3 | Variable b is set to 3 |
| 3 | c | Add a + b | 8 | Sum of 5 and 3 stored in c |
| 4 | d | Multiply a * b | 15 | Product of 5 and 3 stored in d |
| 5 | - | - | - | End of operations |

Variable Tracker
| Variable | Start | After Step 1 | After Step 2 | After Step 3 | After Step 4 | Final |
|---|---|---|---|---|---|---|
| a | undefined | 5 | 5 | 5 | 5 | 5 |
| b | undefined | undefined | 3 | 3 | 3 | 3 |
| c | undefined | undefined | undefined | 8 | 8 | 8 |
| d | undefined | undefined | undefined | undefined | 15 | 15 |
Key Moments - 2 Insights
Why does c become 8 after step 3?
Because c stores the result of adding a (5) and b (3), so 5 + 3 = 8 as shown in execution_table row 3.
Why is d assigned after step 4 and not before?
d is assigned after step 4 because it depends on multiplying a and b, which are assigned in earlier steps (rows 1 and 2).
Visual Quiz - 3 Questions
Test your understanding
Look at the execution_table at step 3, what is the value of c?
💡 Hint
Check the 'Value' column for step 3 in the execution_table.
At which step is variable d assigned a value?
💡 Hint
Look at the 'Step' column and find when d is assigned in the execution_table.
If we change b from 3 to 4, what will be the new value of c at step 3?
💡 Hint
c is a + b, so add a (5) and new b (4) to find c.
Concept Snapshot
Arithmetic operators in MATLAB: Use + for addition, - for subtraction, * for multiplication, / for division, ^ for power. Example: c = a + b adds a and b.
Full Transcript
This visual execution shows how MATLAB uses arithmetic operators. First, variables a and b are assigned values 5 and 3. Then c is assigned the sum of a and b, which is 8. Next, d is assigned the product of a and b, which is 15. The execution table tracks each step and variable value. Key moments clarify why variables get their values at certain steps. The quiz tests understanding of variable values and effects of changes. The snapshot summarizes the main arithmetic operators and usage.
