Hello all,
I am not new with Matlab but I am quite unexpert on dealing with imaging and overlapping.
I have a vector field from my PIV results and I want to overlap it on my PLIF image. Thus, I have a 3D matrix for the PIV (x,y,velocity) that I plot with quiver and a 2D image for PLIF (it is a .SPE file). When I overlap these just by using:
quiver(x,y,x_velocity, y_velocity)
hold on;
imagesc(PLIF_data)
I do not have a good math since the scales are different. How can I have the same scales for these two sets of data?
I do not think it should be a tough task for most of you but I am quite puzzled 'cause I am litterally brand new to this field
Thank you so much

yes，sir，may be use
quiver(x,y,x_velocity, y_velocity)
hold on;
h=imshow(PLIF_data,[])
set(h,'AlphaData',0.5)
