function [r,p] = map1d(xgrid,ygrid,qgrid) % % MAP1D is a user-defined function to create line plots from 2d/3d data % % MAP1D is a user-defined function called by PLOTCLAW2 or PLOTCLAW3 to % convert 2d or 3d data into 1d data for a line plot. % % For 2d data, the MAP1D function has the form % % [r,q] = map1d(xgrid,ygrid,qgrid) % % where XGRID, YGRID, and QGRID are MxN arrays of grid data, and R and % Q are 1d column vectors of user-defined length. % % For 3d data, the MAP1D function has the form % % [r,q] = map1d(xgrid,ygrid,zgrid, qgrid) % % where XGRID, YGRID, ZGRID and QGRID are MxNx{ arrays of grid data, % R and Q are 1d column vectors of user-defined length. % % This function will be called from PLOTCLAW2 or PLOTCLAW3 if % 'UserMap1d' = 1. This plotting parameter can be set in the file % SETPLOT2 or SETPLOT3. % % Example : % % % To plot q as a function of x only ; % function [r,q] = map1d(xgrid,ygrid,qgrid) % % [m,n] = size(xgrid); % r = reshape(xgrid,m*n,1); % q = reshape(qgrid,m*n,1); % % Example : % % % Plot data interpolated to grid diagonal on [0,1]x[0,1]x[0,1] % % grid % function [r,q] = map1d(xgrid,ygrid,zgrid,qgrid) % % r = linspace(0,0.1,1)*sqrt(3); % q = interp3(xgrid,ygrid,zgrid,qgrid,r); % % % NOTE : This help file can also be found by typing 'map1d_help' at % the Matlab prompt % % % See also SETPLOTSTYLE, PLOTFRAME1EZ, GETLEGENDINFO, SETPLOT.
