Interpolation of a dataset from two matrices

T = readtable('torque110.xlsx','ReadV',0);
torquei = T_rpm_new(:,4);
throttle= [0	3	5	10	15	20	30	40	50	60	70	80	90	100];
T = T{:,:};
d = diff(T,1,2);
ad = cumsum(eps(1e3)*~[d,zeros(size(T,1),1)],2);
Tw = T + ad;
out = cellfun(@(x,y)interp1(x,throttle(:),y),num2cell(Tw',1),num2cell(torquei'));

T is Torque matrix of 8727*14. I have the Throttle value of order 1*14. I want to get throttle at torque value of torquei by interpolating it. The code is showing error as following:

Error using griddedInterpolant

The grid vectors must contain unique points.

Error in interp1 (line 161)

F = griddedInterpolant(X,V,method);

Error in test_sch_shifting_map_ex>@(x,y)interp1(x,throttle(:),y)

Error in test_sch_shifting_map_ex (line 166)

out = cellfun(@(x,y)interp1(x,throttle(:),y),num2cell(Tw',1),num2cell(torquei'));

For convenience i am attaching three excel files. I need throttle values at specified torque values of third file.
