The error is due to the square brackets that you used to denote a block for if condition. Square brackets are not required to denote a block in MATLAB.

if(Choice==1)
    fprintf('i(t)=dq/dt\n')
    coeff = input('Please enter the coeffecent before the e:  ');
    exp = input('Please enter the exponent ignoring the t variable:  ');
    coeff1 = coeff * exp;
    fprintf('i(t) = %0fe',r1) 
    fprintf('^ %0t',exp)
elseif(Choice==2)
    % Your code goes here
elseif(Choice==3)
    % Your code goes here
elseif(Choice==4)
    % Your code goes here
end

This code would probably help.
