The way that this file works is that the color of each pixel represents the elevation at a given point. So, the lighter the pixel the higher the elevation, etc. You can read in this image and plot the elevations by doing something like:
>> A = imread('myDSMFile.tif'); % Get elevation data
>> [X, Y] = meshgrid(1:size(A,2), 1:size(A,1)); % Create all (x,y) points to plot
>> mesh(X,Y,A); % Plot the data
The mapping toolbox has a function called "geotiffread" which acts very similarly but it also extracts different information out of the file like geographic location and scale.
