Changes to compiler support for building MEX-files
MATLAB no longer supports the following compilers on Microsoft Windows platforms:
•
Intel
®
C++ Version 11
• Intel Visual Fortran Version 11
• Open Watcom C/C++
Compatibility Considerations
To ensure continued support for building your MEX-files, consider upgrading to another
supported compiler. For an up-to-date list of supported compilers, see the Supported and
Compatible Compilers website.
Changes to time alignment for time series objects
The IsTimeFirst property for time series objects is now read only. The property value
is false for 3-D and higher dimensional data. Otherwise, the value is true.
• true — The first dimension of the data array is aligned with the time vector. For
example, ts = timeseries(rand(3,3),1:3);
• false — The last dimension of the data array is aligned with the time vector. For
example: ts = timeseries(rand(3,4,5),1:5);
Consequently, the alignment of the Time property with the first or last data dimension
of the Data property is based on the number of dimensions of the data. When the data
contains three or more dimensions, the length of the Time property matches the size of
the last data dimension. Otherwise, the length of the Time property matches the size of
the first data dimension.
Compatibility Considerations
You receive an error when creating a time series object with 3-D or higher dimensional
data and with time alignment along the first dimension.
To preserve the property value of true for IsTimeFirst with 3-D or higher
dimensional data, reshape the data array to two dimensions, such that the last
data dimension and the time dimension are compatible. For example, replace
timeseries(ones(10,4,2),1:10) with timeseries(ones(10,8),1:10).
