Index exceeds matrix dimensions

    %SET UP USEFUL VARIABLES
NumControls = 2; %number of control experimetns with no grating
dt = 1; %spacing between samples time point [ms]
t_On = 0; %time stimulus turns on [ms]

%PLOT RASTERS FOR ONE PARTICULAR ANGLE
figure(1)
for trial=1:NumTrials
    plot(t_vect,trial*d(ThisOrientation,:,trial),'+')
    hold on
end

The error hows index exceeds matrix dimensions on the line plot(t_vect,trial*d(ThisOrientation,:,trial),'+')

Tried to figure out myself by browsing all the same error but can't find any. Can anyone please help me since I might be overlooked?

my data size is 4x15x30 double. Thanks a lot!

d(ThisOrientation,:,trial)

The above extracts, ThisOrientatoion row from the 3d matrix trial. YOur ThisOrientation is 15. But your d has only four rows. So the error.

Answer 1

Your ThisOrientation should be less then or equal to the number of rows in d.

ThisOrientation = 4 ;   % it should be less then or equal to 4

It works! Thanks a lot :)
