Resolve Error: Mismatched fimath

Issue

If two fi object operands have an attached fimath, the fimaths must be equal.

Possible Solutions

Use the removefimath function to remove the fimath of one of the variables in just one instance. By removing the fimath, you avoid the “mismatched fimath” error without permanently changing the fimath of the variable.

Function:

function y = mysum(x,T)  %#codegen  
	y = zeros(size(x), 'like', T.y);
   for n = 1:length(x)
        y(:) = y + x(n);
   end
end

Function:

function y = mysum(x,T)  %#codegen  
	y = zeros(size(x), 'like', T.y);
   for n = 1:length(x)
          y(:) = removefimath(y) + x(n);
   end
end

Types Table:

function T = mytypes(dt)
	switch(dt)
        case 'fixed'
        T.x = fi([],1,16,0, 'RoundingMethod', 'Floor',...
	     'OverflowAction','Wrap');
        T.y = fi([],1,16,0, 'RoundingMethod','Nearest');
    end
end
