M2SCI function
mtlb_diff - Matlab diff emulation function
Description
Matlab and Scilab
diff
behave differently in some particular cases:
-
-
-
With two input parameters: Scilab
diff
considers all values of first input as a vector
what Matlab does not.
-
With three input parameters: If dimension of first input along dimension given by third parameter
reaches 1 before n interations
have been made,Matlab switches to next non-singleton dimension what Scilab does not.
The function
mtlb_diff(A[,n[,dim]])
is used by
mfile2sci
to replace
diff(A[,n[,dim]])
when it was not
possible to know what were the inputs while porting Matlab code to Scilab. This function will
determine the correct semantic at run time. If you want to have a
more efficient code it is possible to replace
mtlb_diff
calls:
-
-
-
With two inputs, if
A
is a scalar or a vector
mtlb_diff(A,n)
may be replaced by
diff(A,n)
-
With three inputs, if size of A along dimension given by
dim
can not reach 1
mtlb_diff(A,n,dim)
may be replaced by
diff(A,n,dim)
Caution:
mtlb_diff
has not to be used for hand coded functions.
