Instrfind will not find an object with a Name property value of

'myobject'. However, properties which have an enumerated list data type

will not be case sensitive when searching for property values. For

example, INSTRFIND will find an object with a Parity property value

of 'Even' or 'even'.

Example:

s1 = serial('COM1', 'Tag', 'Oscilloscope');

s2 = serial('COM2', 'Tag', 'FunctionGenerator');

set(s1, 'ObjectVisibility', 'off');

out1 = instrfind('Type', 'serial')

out2 = instrfindall('Type', 'serial');

<instrfind> - Find serial port objects with specified property values.

INSTRFIND Find serial port objects with specified property values.

OUT = INSTRFIND returns all serial port objects that exist in memory.

The serial port objects are returned as an array to OUT.

OUT = INSTRFIND('P1', V1, 'P2', V2,...) returns an array, OUT, of

serial port objects whose property names and property values match

those passed as param-value pairs, P1, V1, P2, V2,... The param-value

pairs can be specified as a cell array.

OUT = INSTRFIND(S) returns an array, OUT, of serial port objects whose

property values match those defined in structure S whose field names

are serial port object property names and the field values are the

requested property values.

OUT = INSTRFIND(OBJ, 'P1', V1, 'P2', V2,...) restricts the search for

matching param-value pairs to the serial port objects listed in OBJ.

OBJ can be an array of serial port objects.

Note that it is permissible to use param-value string pairs, structures,

and param-value cell array pairs in the same call to INSTRFIND.

When a property value is specified, it must use the same format as

GET returns. For example, if GET returns the Name as 'MyObject',

Instrfind will not find an object with a Name property value of

'myobject'. However, properties which have an enumerated list data type

will not be case sensitive when searching for property values. For

example, INSTRFIND will find an object with a Parity property value

of 'Even' or 'even'.

Example:

s1 = serial('COM1', 'Tag', 'Oscilloscope');

s2 = serial('COM2', 'Tag', 'FunctionGenerator');

out1 = instrfind('Type', 'serial')

out2 = instrfind('Tag', 'Oscilloscope')

out3 = instrfind({'Port', 'Tag'}, {'COM2', 'FunctionGenerator'})

<timerfindall> - Find all timer objects with specified property values.

TIMERFINDALL Find all timer objects with specified property values.

OUT = TIMERFINDALL returns all timer objects that exist in memory

regardless of the object's ObjectVisibility property value. The timer

objects are returned as an array to OUT.

OUT = TIMERFINDALL('P1', V1, 'P2', V2,...) returns an array, OUT, of

timer objects whose property names and property values match those

passed as param-value pairs, P1, V1, P2, V2,... The param-value pairs

can be specified as a cell array.

OUT = TIMERFINDALL(S) returns an array, OUT, of timer objects whose

property values match those defined in structure S whose field names

are timer object property names and the field values are the requested

property values.

OUT = TIMERFINDALL(OBJ, 'P1', V1, 'P2', V2,...) restricts the search for

matching param-value pairs to the timer objects listed in OBJ. OBJ can

be an array of timer objects.

Note that it is permissible to use param-value string pairs, structures,

and param-value cell array pairs in the same call to TIMERFINDALL.

When a property value is specified, it must use the same format as

GET returns. For example, if GET returns the Name as 'MyObject',

TIMERFINDALL will not find an object with a Name property value of

'myobject'. However, properties which have an enumerated list data type

will not be case sensitive when searching for property values. For

example, TIMERFINDALL will find an object with a Parity property value

of 'FixedRate' or 'fixedrate'.

Example:

t1 = timer('Tag', 'broadcastProgress', 'Period', 5);

t2 = timer('Tag', 'displayProgress');

out1 = timerfindall('Tag', 'displayProgress')

out2 = timerfindall({'Period', 'Tag'}, {5, 'broadcastProgress'})
