Let’s look at some examples:
Note: If you have lost the “[“ symbol that denotes the calculation (input) field, add
it by selecting from the top menu Insert -> Calculation.
Computing with numbers
MuPAD returns integer results or rational results, when integers and rational
numbers are computed. For example:
The variable DIGITS indicate how many significant digits will go into computation.
Float command finds a floating point approximation for an expression. For
example:
Differentiation and Integration
To compute the derivative, use the diff command.
To compute the integral, use int command.
For example:
Solving Equations
Use a solve command to solve algebraic equations. For example:
Moreover, you can solve equations with symbolic parameters. For example:
Plotting
To plot a simple 2-D plot, use a plot command. For example:
If you want to plot several functions on the same figure, you should list all the functions
and separate them by commas. MuPad will display functions in multiple colors:
