How can I get data from evaluating a function, say y=x^2+5 for x=0.1 to 0.9 for 50 points in between and put it in table?

x = linspace(0.1,0.9,50);
y = x.^2+5;
tbl = table(y.');

The semicolon at the end of a line of MATLAB code suppresses the output. So just leave the semicolon off of any line you want displayed to the command window.
x = linspace(0.1,0.9,50)
x = 1×50

These are very basic MATLAB questions. You might want to watch the MATLAB Onramp tutorial.
