344 Introduction to C++ Programming and Graphics
- Beginning and end of a command line:
AMatlabcommand can begin at any position in a line, and may continue
practically indefinitely in the same line. - Line continuation:
To continue a command onto the next line, we put three dots at the end
of the line. - Multiple commands in a line:
Two or more commands can be placed in the same line provided they are
separated with a semicolon (;). - Display:
When a command is executed directly or by running aMatlabcode,
Matlabdisplays the numerical value assignment or the result of a calcu-
lation. To suppress the output, we put a semicolon (;) at the end of the
command. - White space:
More than one empty space between words are ignored by the compiler.
However, numbers cannot be split in sections separated by blank spaces. - Range of indices:
Vectors and arrays must have positive and non-zero indices; the vector
entryv(-3)is unacceptable inMatlab. This annoying restriction can
be circumvented in clever ways by redefining the indices. - Comments:
A line beginning with the%character, or the tail-end of a line after the%
character, is a comment, and is ignored by theMatlabinterpreter. - Mathematical symbols and special characters:
Table F.1.1 lists mathematical symbols and special characters used in
Matlabinteractive dialog and programming. - Logical control flow commands:
Table F.1.2 lists the basic logical control flow commands. - Input/Output commands:
Tables F.1.3-5 list basic Input/Output (I/O) commands, functions, and
formatting statements. Once the output format is set, it remains in effect
until changed.
