I am getting an error message when I try to plot this, but MatLab does not specify what the problem is. Thanks.
GL4_Strm = xlsread('GL4_Stream.xlsx');
GL4_endm = xlsread('GL4_Endmember.xlsx');
scatterplot(GL4_Strm,GL4_endm);

Please post the entire error message.
Also, if you could upload the data files (or a smaller version that reproduces the error), that would be helpful.

The error message is:
Operands to the || and && operators must be convertible to logical scalar values.
Error in scatterplot (line 60)
if ((fix(n) ~= n) || (n <= 0))
Error in GL4_EMMA (line 17)
scatterplot(GL4_Strm,GL4_endm);

What are the sizes (dimensions) of ‘GL4_Strm’ and ‘GL4_endm’?

GL4_Strm is 26x15 double, and GL4_endm is 74x16 double.

The scatter function requires two equal-length vectors. There is no way you can plot those two matrices even if you created vectors out of them. They have different sizes, and different numbers of elements.

Thanks! I was able to eliminate some null values that were floating around and use the reshape function.

My pleasure!
Now I wish I’d posted this as an Answer!
