The initial value specified for global variable XXX is not contained by the global variable's type

I have defined the variable right after. Any idea?

Thanks.

You tried to initialize a global variable to a value that cannot be represented by the datatype of that variable. For example you might have defined the variable as int8 but tried to initialize it to 255 (which would fit in uint8 but not in int8)

Thanks Walter and Preethi for quick responses. Feels like a true community! :)

As I said earlier, I had the variable X defined as global and fill it with a X = zeros(7,7) so matlab coder get it how I want to use it later in C. However, it kept on giving me that error. I managed to get rid of the error by doing the first allocation as X = 0; !!! and that has not giving me any error even though I am still using the variable X down the code as a 7x7 matrix. Giving this that I have not been able to run the C code yet as I working on other parts of it.

Even though I have managed to fix the error, I am still curious to know what is the cause for it or if Walter still has the same opinion.

Thanks,
