I'm interested in looking at graphing the phase portraits of 2x2 autonomous ODEs, and I'm using the StreamPlot
function.
Here is one simple example:
StreamPlot[{-y, -2 x}, {x, -5, 5}, {y, -5, 5}]
I'm finding it very tedious to continue typing , {x,-5,5}, {-5,5}
etc. as part of every separate plot I construct. Is there some faster way to input my range? I don't want to have to rely on ctrl c ctrl v etc.
I'm sorry if this is a silly question!
