WHO Describe Currently Defined Variables
Section: Inspection Functions
UsageReports information on either all variables in the current context or on a specified set of variables. For each variable, the
whofunction indicates the size and type of the variable as well as if it is a global or persistent. There are two formats for the function call. The first is the explicit form, in which a list of variables are provided:
who a1 a2 ...
In the second form
who function lists all variables defined in the current
context (as well as global and persistent variables). Note that
there are two alternate forms for calling the
who 'a1' 'a2' ...
ExampleHere is an example of the general use of
who, which lists all of the variables defined.
--> c = [1,2,3]; --> f = 'hello'; --> p = randn(1,256); --> who Variable Name Type Flags Size c double [1 3] f char [1 5] p double [1 256]
In the second case, we examine only a specific variable:
--> who c Variable Name Type Flags Size c double [1 3] --> who('c') Variable Name Type Flags Size c double [1 3]
