MATLAB: Square wave

RESOLUTION = 1000;   %whatever is appropriate
DUTYCYCLE = 0.73;    %e.g. 73% on, 27% off
NUMBEROFCYCLES = 18;  %as appropriate
basepulse = ones(1,RESOLUTION);
squarepulse = basepulse;
squarepulse(floor(DUTYCYCLE * RESOLUTION) + 1 : end) = 0;
wavetrain = repmat(squarepulse, 1, NUMBEROFCYCLES);

[GIS] Specify world file to use in ArcGIS

If the message you see is something like "you are missing a Spatial Reference", then the world file is alright. The world file cannot define the SR (spatial reference). To do this, right-click your image in Catalog, select Properties, scroll down to the Spatial Reference section, click "Edit" to define the Spatial Reference. This will generate a *.aux.xml file (for BMP) containing the SR information. Now, as you add the BMP image to ArcMap, you will not see the "missing SR" message.
