Combining two strings

I'm using uigetfile to get the path and file name of a data file which enables me to use the load command to import the data. For example, say the file is named channel1.txt.

Inside the multi-column data file is a column that has receiver number. I save that receiver number as a string, we'll say it is 1.

When I plot the data, I want the legend to say "Rx 1 channel1.txt". Currently I just am doing legend(filename1) which would show "channel1.txt." How can I combine all of these strings to 1 legend label?

plot(randn(100,1));
filename = 'channel1.txt';
Rx = 'Rx 1';
legend([Rx filename]);
% or
legend(strcat(Rx,filename));
