How do I save a figure to a different directory with a specific figure name?

I am trying to save a figure with the type and dateTime variables included in the savefile name. My code uses the input variable " type = 'Triangle' " in order to run, and it saves the start time as a dateTime variable. I want the "type" variable to save based on it's input so that the saved figure will include any string assigned to "type." I am also trying to save the figure to a different directory.

I have a code that uses the variable " type = 'Triangle' " when running the code and saves the time I start running the code as f. I want to save that string variable with the date & time as part of the figure name. I'm trying to also save this figure to a different directory that my code is not in.

This is what I have so far but I am getting the following error: H must be an array of handles to valid figures.

type = 'Triangle';

folderName = 'C:\my\directory';

savefig(fullfile(folderName,[datestr(startTime) type]));

savefig(FILENAME) saves the current figure to a file named FILENAME

savefig(H, FILENAME) saves the figures identified by the graphics

handle array H to a MATLAB figure file called FILENAME.

To be robust, specify H and make sure your file name is valid.

H=figure
plot(1:10)
savefig(H, 'myFigure')
