Curve fitting (Graphical)

Graphical interface for the previous command based program was implemented with the help of GTK3 library. Install GTK3 library and then compile the program Curve_fit.c as follows,

export PKG_CONFIG_PATH='/home/Software/GTK3/Library/GTK3/lib/pkgconfig'
gcc -o Curve_fit Curve_fit.c `pkg-config --cflags --libs gtk+-3.0` -lm -lgsl -lgslcblas

or explicitly

gcc -o Curve_fit Curve_fit.c  -lpthread -I/usr/include -I/home/Software/GTK3/Library/GTK3/include/gtk-3.0 -I/home/Software/GTK3/Library/GTK3/include/atk-1.0 -I/home/Software/GTK3/Library/GTK3/include/at-spi2-atk/2.0 -I/home/Software/GTK3/Library/GTK3/include/pango-1.0 -I/home/Software/GTK3/Library/GTK3/include/gio-unix-2.0/ -I/home/Software/GTK3/Library/GTK3/include/cairo -I/home/Software/GTK3/Library/GTK3/include/gdk-pixbuf-2.0 -I/home/Software/GTK3/Library/GTK3/include/glib-2.0 -I/home/Software/GTK3/Library/GTK3/lib/glib-2.0/include -I/home/Software/GTK3/Library/GTK3/include/at-spi-2.0 -I/home/Software/GTK3/Library/GTK3/include/dbus-1.0 -I/home/Software/GTK3/Library/GTK3/lib/dbus-1.0/include -I/home/Software/GTK3/Library/GTK3/include/harfbuzz -I/home/Software/GTK3/Library/GTK3/include -I/usr/include/freetype2 -I/home/Software/GTK3/Library/GTK3/include/pixman-1 -I/usr/include/libpng12  -L/home/Software/GTK3/Library/GTK3/lib -lgtk-3 -lgdk-3 -latk-1.0 -lgio-2.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo-gobject -lpango-1.0 -lcairo -lgobject-2.0 -lglib-2.0 -lm -lgsl -lgslcblas

As explained for command based program, the graphical based progrm also require two input files namely, Data and Limit. By clicking the "Data" / "Limit" button on the left pane editable notebook tab will be opened where the input files can be prepared by either typing or copying the entry from an excel sheet. After the entry, the files are saved under the name "Data" and Limit" in the same folder where the program executable is present aswellas run.

On completion of the preparation of input files, choose the model by clicking  "function" button. Then run the program by clicking "Run" button. On completion of the fitting, go through the results by clicking "Results" button. Plot the graph by clicking the "plot" button.

(Separate folders for each models has been given for testing purpose. The input files for each models are present within it.)
