If a function does not return any output by definition, a zero output value will be inserted to
the stack. For example, if the function func is declared with no output arguments, the
expression func( ) + 3 is legal because func returns zero by default.
Example:
float vec[11], RA[100];
Declare the global variables.
float value;
Declare the global variable.
function [float mean, float std]=statistic();
Function prototype.
…
[RS[1],RA[2]]=statistic()
Call the statistic function. After
execution, RA[1] will be equal to
variable mean and RA[2] will be
equal to variable std.
[value]=statistic()
In this case, after executing the
statistic function, value will be equal
to variable mean.
…
function [float mean, float std]=statistic();
Declare a function that calculates
mean and standard deviation of the
global vector vec.
int k;
Declare k as automatic variable.
global vec[11];
Redeclare for vec variable (vec is
global variable previously
declared).
mean=0;
for k = 1:10
mean = mean + vec[k];
End
mean = mean/10;
Calculate mean of vec[ ]
if (nargout>1)
Only if standard deviation is
queried . . .
std = 0;
for k = 1:10
std = std + vec[k] * vec [k];
End
st = (1/10) * ssrt. (std – 10 * mean)
End
Return
End of function body

For count of input arguments, the number of input arguments during a function call must be
the same as declared during the function definition.
