Trying to normalise my data to 101 points but receiving the error: Error using griddedInterpolant Interpolation requires at least two sample points in each dimension.
Error in interp1 (line 186) F = griddedInterpolant(X,V,method); Using the code: Number_of_Steps = length(Touch_Down);
for i=1:Number_of_Steps data=mm3(Touch_Down(i,1):Toe_Off(i,1),2); %data is used from one starting point to the next starting point filt_pressure(:,i)=interp1(1 : length(data) , data , linspace(1, length(data),100)); %interp1(original structure, values , new structure end;
When running the code it interpolates a few columns of data for the filt_pressure but does not interpolate every single one of them and I'm not sure why.
Any help is much appreciated.

READ THE ERRORR MESSAGE! LOOK AT YOUR DATA!
[Touch_Down,Toe_Off]
ans =
218 225

285 285
287 287

You have this:
data=mm3(Touch_Down(i,1):Toe_Off(i,1),2);
How long is the vector:
Touch_Down(i,1):Toe_Off(i,1)
when i == 4, or 5, or 6? In those cases, what is length(data)?
Now go back and re-read the error message.
