[BUG] Error in matRad_interp1

[ferdymercury]

Describe the bug
I am using this script https://github.com/SebastiaanBreedveld/TROTS/blob/master/Scripts%20matRad/readTROTSPatient.m to load the "Protons01.mat" dataset into matRad. https://zenodo.org/records/2708302/files/Protons.zip?download=1

Optimization works fine and I get sensible DVH results. But when I run matRad_calcQualityIndicators, I get an interpolation? error.

@tobiasbecher @wahln any help is welcome, thanks in advance.

Index in position 1 exceeds array bounds. Index must not exceed 1.

Error in matRad_interp1 (line 66)
        y = yi(ix1,:) + ( yi(ix2,:)-yi(ix1,:) ) * ( x - xi(ix1) ) / ( xi(ix2) - xi(ix1) );

Error in matRad_calcQualityIndicators>@(x)matRad_interp1(linspace(0,1,numOfVoxels),doseInVoi,(100-x)*0.01) (line 75)
        DX = @(x) matRad_interp1(linspace(0,1,numOfVoxels),doseInVoi,(100-x)*0.01);

Error in matRad_calcQualityIndicators (line 80)
            qi(runVoi).(strcat('D_',num2str(refVol(runDX)))) = DX(refVol(runDX));

Error in readTROTSPatient4 (line 272)
qi  = matRad_calcQualityIndicators(cst, pln, resultGUI.physicalDose);

To Reproduce
Steps to reproduce the behavior:

1. Download https://zenodo.org/records/2708302/files/Protons.zip?download=1
2. Extract Protons01 file
3. Get https://github.com/SebastiaanBreedveld/TROTS/blob/master/Scripts%20matRad/readTROTSPatient.m
4. Run script

Expected behavior
No error is shown.

If I update git to latest version, I get instead a different error earlier on:
