I'm using a script to take these x and y values from a .txt file. At this point in the script the variables are assigned the fid is closed… When I code further, I'm trying to interpolate a user entered value which is called 'userx'.
Below, though, I am just trying to get it to interpolate at 100. I don't understand where my syntax error is.
>> x
x =
0 20 22 30 33 52 52 67 84 101 103 111 116 132 141 159 162 168 171 173
>> y
y =
8477 11886 11384 6087 7871 3003 1941 9213 10981 2179 2219 507 1593 8880 11650 4392 6118 4437 2094 1961
>> interp1(x,y,100) Error using interp1 (line 130) Values must be of type double or single.
