What is the limit of this infinite exponential? Solution 1: $$x=\sqrt{2}^x$$ This leads to x=2 or 4 Solution 2: $$x=^x$$ This leads to x not equal to 2 or 4 Solution 3: MatLab simulation of series $$\sqrt{2}, \sqrt{2}^\sqrt{2}, [\s
I find saveppt2 is very useful in data exploration. I often have to view a lot of plots/figures for individual subjects during quality checking or data exploration. It would be ideal to have a script to automatically save the plots into PowerPoint an
