whenever i run the program it says 'Error using interpDriveCycle (line 10) Not enough input arguments. '

function [a,s] = interpDriveCycle(t, v)

%interpDriveCycle Produce accelerations that go with drive cycles.

% a = interpDriveCycle(t, v) produces a constant acceleration to go with

% the drive cycle data described by (t, v). A constant acceleration is

% assumed between each point in the cycle.

% Check input parameters:

assert(isvector(t), 'interpDriveCycle:inputsNotVectors', ... 'Inputs not vectors: t and v must be row or column vectors.');

sizeT = size(t);

sizeV = size(v);

sizesAreEqual = isequal(sizeT, sizeV);

assert(sizesAreEqual, 'interpDriveCycle:inputSizesNotEqual', ... 'Input sizes not equal: t and v must have the same dimensions.');

% Convert to column vector form:

t = t(:);

v = v(:);

% Calculate the accerations:

deltaT = [t(2:end) - t(1:end-1); 1];

deltaV = [v(2:end) - v(1:end-1); 0];

a = deltaV ./ deltaT;

% Calculate the displacements.

s = zeros(size(t));

for iPoint = 1:numel(s)-1

    thisS = s(iPoint);

    thisV = v(iPoint);

    thisA = a(iPoint);

    deltaT = t(iPoint+1)-t(iPoint);

    nextS = thisS + thisV * deltaT +0.5*thisA*deltaT*deltaT;

    s(iPoint+1)= nextS;

end

a = reshape(a, sizeT);

s = reshape(s, sizeT);

end

Same as in the previous case. What are you trying to do?
