+Compile code with:
+
+ make
+
+Set $COILSDIR with path to 'new.mat' file. e.g. in bash:
+
+ export COILSDIR=/path/to/matrix
+
+Run code with:
+
+ ./ncoils
+
+
+OLD INFO
+--------
+
+Either re-compile the program as (e.g.)
+
+cc -O2 -I. -o ncoils-osf ncoils.c read_matrix.c -lm
+
+or use the exectuables (ncoils-osf, ncoils-irix) given.
+
+Move the executables to a central bin directory and re-name
+as appropriate.
+
+You then need to set an environment variable $COILSDIR to this directory
+so that matrices can be seen.
