The surf function creates surfaces based on four points. But for the edge of the sample data below, there are only three points available. Is there a better way to plot this surface or is there a clever way to alter the surf function to use three points when that's all that's available?

x = [    
    23    25    34    36    40;
    45    50    56    70   NaN;
    44    55    66   NaN   NaN;
    57    70   NaN   NaN   NaN;
    61   NaN   NaN   NaN   NaN;
    ];
surf(x)
