System object: dsp.MatFileReader
Read data from a variable in the MAT file
X = step(mfr)
Starting in R2016b, instead of using the
to perform the operation defined by the System
object™, you can
call the object with arguments, as if it were a function. For example,
= step(obj) and
y = obj() perform equivalent
X = step(mfr) reads
X, from a variable stored in a MAT-file.
The variable is assumed to be N-dimensional and
a MATLAB built-in datatype. The data is read into MATLAB by reading
along the first dimension.
obj specifies the System
which to run this
The object performs an initialization the first time the
is executed. This initialization locks nontunable
properties (MATLAB) and input specifications, such as dimensions, complexity,
and data type of the input data. If you change a nontunable property
or an input specification, the System
object issues an error.
To change nontunable properties or inputs, you must first call the
to unlock the object.
