I want to increase the number of decimal places a figure can accurately be shown in an entry of a Matrix, using fprintf it shows all entries up to 4dp but how can I increase the d.p?
Thanks
Joe

Say A is the matrix fprintf('%10.7f',X) I understand 10 to be the spacing -character width and 7 related to the dp but the matrix i get is only to 4d.p.

What is a "Matrix" for this purpose?
What format are you using with fprintf() ?
fprintf('%.999g\n', pi)

3.1415927
Is what you are doing like
A = fprintf('%10.7f', pi);
If it is then what is being stored in A is the number of elements output, not the string. If you want the string use sprintf
A = sprintf('%10.7f', pi);
