Hi,

I have a vector of uint8, going into an embedded function

The vector looks like that and his size may change

10
15
79
189
77
66
32
0

What i want is 1015791897766320 in double.

Is there a way to do that.??

Thank you

I found a way to do that in my work space:

>> u = [1 2 5 7 8 9]

u =

1 2 5 7 8 9

>> sprintf('%g',u)

ans =

125789

But now, when i try to put that in an embedded function, I get this error :

Function 'sprintf' implicitly resolved in the MATLAB workspace. Implicit evaluation in MATLAB is not supported. Please declare this function extrinsic using eml.extrinsic('sprintf'), or call it using feval.

Function 'Embedded MATLAB Function' (#91.28.43), line 7, column 4:
"sprintf('%g',u)"
Launch diagnostic report.


How can I repair that? Do i have to call a specific library (like the math library in JAVA)??

Thx for your help

There's no guarantee that the value you want to construct from the vector is
exactly representable in double precision, is there?

v = [uint8(1); zeros(200, 1, 'uint8')]
