IMPORTANT: Download the .zip package in order to get the .mat locations of the default channels.

The 'plot_topography' function plots a topographical EEG/MEG map of the head over the desired points (ch_list) and their assigned (values). Note that the channels must be introduced according to their names, following the 10-10, 10-20 or the Yokogawa system. If you want to use custom locations, you must indicate the path of a locations.mat file (see the header of the function for further instructions).

Input parameters:
- ch_list: Channel list in cell-array. Use the string 'all' for displaying all channels available. Note that 'z' indicator should be in lower case. Example: ch_list = {'Fpz','Fz','Cz','Pz','Oz'};
- values: Numeric vector that contains the values assigned to each channel.
- make_contour: (Optional, default: false) Boolean that controls if the contour lines should be plotted.
- system: (Optional) Measurement system as a string: '10-20' (default), '10-10', 'yokogawa', custom path or table.
- plot_channels: (Optional, default: false) Boolean that controls if the electrodes should be plotted.
- plot_clabels: (Optional, default: false) Boolean that controls if the text labels of each electrode should be plotted.
- INTERP_POINTS:(Optional, default: 1000) No. of interpolation points. The lower N, the lower the resolution and the faster the computation.

Example of use:
plot_topography('all', rand(1,81));
