FitGeoTransform- moving point and fixed points not working into function

I have found the co-ordinates of both my FixedPoints and my Moving points.

The output for my Moving :

MovingPoints =

33.9008 380.1554

80.2401 26.5201

106.6683 452.9590

445.4878 391.7935

and my fixed:

FixedPoints =

26.5000 445.5000

26.5000 26.5000

26.5000 445.5000

445.5000 445.5000

however when I'm applying the function of fitgeotrans i get the error:

Error using fitgeotrans>findProjectiveTransform (line 187)

At least 4 non-collinear points needed to infer projective transform.

Error in fitgeotrans (line 100)

tform = findProjectiveTransform(movingPoints,fixedPoints);

Error in Reportprogress (line 74)

t = fitgeotrans(MovingPoints,FixedPoints,"projective")

I have no idea why it says ther are no 4 points when my FP and MP each have 4 co-ordinates...

Thank you for your time.

The points are the rows of your matrices, and in the FixedPoints matrix,

(26.5000  445.5000) and (26.5000  445.5000) 

as well as

(26.5000   26.5000) and (445.5000  445.5000)

are collinear.

Could you possibly assist me with a solutions for this?

I'm faily new to Matlab

something like : if the two co-ordinates are equal then +0.05 to one of the co-ordinates?

Thank you

Does it work in the case

FixedPoints =
26.5000  445.5000
26.5000   26.5000
26.5000  445.5500
445.5000  445.5500

?

No that didnt work. However my code for geting the FixedPoint and MovingPoint were used by the reshape.

When using the vec2mat instead, it has worked? :/

Is there any reason for this?

Reshape : FixedPoints = reshape(Centroid,[],2)

Vecmat : FixedPoints=vec2mat(Centroid,2)

what is Centroid output？
