Choosing decimal places by user input.

I was trying to write a code where I can ask the user to choose the number of decimal he/she wants to use when calculating the min or max of vector. But I am really stuck
I was trying to do what below but it doesn't work.
decimal = input('Type the number of decimals places to show in output:');
vector = [23 28 4.29 40.2 8];
min_ = min(Vector);
fprintf('\nMininum: %0.(%0.f)f',min_,decimal);

decimal = input('Type the number of decimals places to show in output:');
vector = [23 28 4.29 40.2 8];
min_ = min(Vector);
fprintf('\nMininum: %0.*f', decimal, min_);
The * in the format signals that the number of decimal places should be extracted from the parameters.

Nice. Was unaware of that functionality (and missed it when I scanned the documentation).

I don't know if you can get the formatSpec itself as an input, so instead you can embed the formatSpec as a separate call to sprintf:
decimal = input('Type the number of decimals places to show in output:');
vector = [23 28 4.29 40.2 8];
min_ = min(vector);
fprintf(['\nMininum: %0.',sprintf('%d',decimal),'f\n'],min_);
