On page 7-29, in “Correcting Problems and Ending Debugging, Completing the
Example,” step 3 is incorrect. It should instead read
“In collatzplot.m line 12,
change the string
plot_seq to seq_length(m) and save the file.”
interp1 Extrapolation of Out-of-Range Values
A new argument enables interp1 to perform extrapolation for out-of-range
values for all methods. It also enables you to specify a scalar to be returned for
out-of-range values.
The PDF version of the interp1 reference page incorrectly states that the
default for all methods is for
interp1 to perform extrapolation for out-of-range
values. In fact,
interp1 performs extrapolation as the default only for the
'spline', 'pchip', and 'cubic' methods. For all other methods, it returns NaN
for out-of-range values. This behavior is unchanged from Version 5.
The HTML reference page for
interp1 is correct.
