Hello everyone!

I need to re-wite a little banch of code for Embedded Coder wich has no support of variable-size arrays.

For my Harware-target I could not enable the support of variable-sized arrays.

Could you please suggest, how I can do it in the most efficient way?

function [seconds, minutes, hours, days, months, years] = fcn(posixTime)
date = datetime(posixTime,'ConvertFrom','posixtime');
[years, months, days] = ymd(date); % <-- Logical indexing requires support of variable-sized arrays, which is currently disabled for code generation.
[hours, minutes, seconds] = hms(date); % <-- Logical indexing requires support of variable-sized arrays, which is currently disabled for code generation.
end

Hi Dimitri,

It is possible to Enable & Disable the Support for Variable-Size Arrays.

Please refer the following documentation for details on Code Generation for Variable-Size Arrays and how to enable the Support for Variable-size arrays in Code Generation:
