diff scripts/plot/errorbar.m @ 17443:4a6a4657fdf2
Overhaul errorbar family of functions.
* scripts/plot/errorbar.m: Add %!error tests for input validation.
* scripts/plot/private/__errcomm__.m: Correctly validate that numeric inputs
are numeric. More precise error reporting indicating the problematic argument.
* scripts/plot/private/__errplot__.m: Fix automatic color cycling for matrices
with multiple columns of data. Check "yerr" case first in if/elseif trees
since it is the most common. Pull static computations out of for loop for
performance.
