Variable Size signal and upper bounds
5 visualizzazioni (ultimi 30 giorni)

Hi, I have this simple exemplary code in a Matlab Embedded Simulink Function (Matlab 2012b)
function y = myfun(n)
coder.varsize('y', [1 1024]);
y = zeros(1,n);
I have also declared y to be a variable-size output.
But when running the model he keeps complaining:
"Output 'y' (#404) has variable size but the upper bound is not specified; explicit upper bound must be provided."
What am I doing wrong?
Thanks for your kind help.
Chris

hello, i am also getting the same error but here i am passing image information to output in simulink ..
i defined
coder.varsize('y4',[0,255]);
where, y4 = [ x1, x2, x3, x4];
where, x1 = im2double(I1);
where, I1 = imread('one.jpg');
similar for x2,x3 and x4 also with their respective I2, I3, I4 values and then y4 passed to video viewer block
where i am failing to solve it ?

You can work around it by:
function y = myfun(n)
assert (n <= 6);
y = zeros(1,n);
you should set the upper bounds for the output ("Y") in the "Edit Data" ("Size" section) and of course you should check the "Variable Size" checkbox.
