Hi, i'm trying to use HDL coder tool.
I used Matlab function block and make a simple as belowed:
function y = fcn(en,in,clk)
z= int16(zeros(9,9));
y = int16(zeros(0));
if clk ==1
if en ==1
for i=0:9
for j=0:9
z(i,j) =in;
end
end
end
y=z(1,1);
end
and when i generate to RTL code (verilog), the always loop is used en and clk singnal for the trigger
always @(clk && en) begin
.......
I expected as belowed
alsways @(posedge clk) begin
if (en) begin
......
If any have experience please help me.
Thank you and best regards.

HDL Coder automatically infers clock, clocken, reset from the model. The inputs to MATLAB function block are pure data inputs.
