so i have a function for exampe h= help(n,x)
h= 2 * help(n-1,x) + help(n-2,x) which should work only when -3<x<3 and n>=2.
and i want it such that when the conditions isnt fulfilled, disp(error: x is outside intervall) and/or disp(error: n is smaller than 2)
so when only x is wrong, only 'error: x is outside intervall' shows.
when only n is wrong, only 'error: n is smaller than 2' shows.
but if both x and n are wrong, then both statements are shown.

if ~(( x > -3) & (x < 3))
error("Please check the value of x ")
end
if ~(n>=2)
error("Please check the value of n")
end
end

but then when both n and x are wrong, only 'Please check the value of x' is given.
I need it such that when both conditions are not met, both reasons/errors are given.

but if i do it this way,
function h= help(n,x)
if ~(( x > -3) & (x < 3))
error("Please check the value of x ")
end
if ~(n>=2)
error("Please check the value of n")
else
h= 2 * help(n-1,x) + help(n-2,x)
end
end
when x condition is not met, but condition of n is, it shows: 'Please check the value of x' and the answer.
I need it such that, when both conditions are not met, both error are shown.
when only one condition is not met, one of the error is shown, but the equation is not calculated.
when both condition is not met, the equeation is calculated.
