why does strel failed in MATLAB Coder

Using MATLAB Coder in 2019b, the following line:

se = strel('line',20,85);

that MATLAB Coder is unable to effectively describe:

1.All inputs must be constant.

2.Function call failed

why is Coder having difficulty in strel?

does matlab coder support strel?

Answer 1

[Pratheek Punchathody]

strel supports the generation of C code (requires MATLAB® Coder™). However,

• All input arguments must be compile-time constants.
• The methods associated with strel objects are not supported in code generation.
• Arrays of strel objects are not supported.

For more information regarding the limitations and known issues please refer to the documentation
