How to do an interpolation on a matrix?

Hello, I used acceleration and position sensors to measure average walking pace. I entered the values ​​in the acceleration time table into variable X, to perform an interpolation, but I get an error

x=timetable2table(Acceleration,'ConvertRowTimes',false);
tmax=50;
t=0:0.1:tmax;
TS=0.05;
steps=interp1(t,x,TS);

hello

I don't think that interp1 works directly on tables

try convert x to array using table2array

You can convert table to array using table2array. You can access the column of table using x.(1).

x=timetable2table(Acceleration,'ConvertRowTimes',false);
tmax=50;
t=0:0.1:tmax;
TS=0.05;
steps=interp1(t,x.(1),TS);
