Any recommendations to remove all infinite values from ydata and then remove those same indices from the xdata so the vectors remain the same length? I have removed the infinite values from the ydata and then outputed the indices that are finite, but I am unsure how to easily extract these same indices from the xdata. Thank you

x = isinf(ydata);
ydata(x) = [];
xdata(x) = [];
Or, if you need to extract the values into new variables,
x = ~isinf(ydata);
ydata_new = ydata(x);
xdata_new = xdata(x);
