What is the error?

You have total of 49 sets of points, which you can not plot via plot3. The number of inputs, to plot multiple set of data, must be a divisible of 3.

Going through the pattern of the input (displayed in form of rows here), the last set of points i.e. [90 1.25 0.07809], seems to be extra.

And there is a typo in defining numbers in numbers in the 29th set (4th row, 2nd set), you have used a comma instead of decimal point.

plot3() works fine after removing the extra data set and correcting the typo.

plot3([40 1.25 0.01107],[40 2.5 0.02238],[40 5 0.04485],[40 10 0.08865],[40 12.5 0.1108],[40 20 0.1772],[40 25 0.2215],[40 40 0.3551],[40 50 0.4431],...
