Question

Write a short piece of MATLAB code that will:

Ask a user for a value, R.

Generate the message: The square root of X.XXX is Y.YYY, if R is non-negative.

If R is negative, the code should generate the message: R is negative. The square root of X.XXX is Y.YYYi [imaginary number]

The value of R should be substituted for X.XXX, and the value of the square root of the magnitude of R should be substituted for Y.YYY. Both numbers should be displayed with three decimal places. For this question, use values where -10 < R < 10.

HINT: Need to use input statement and if / else statement to make sure values are within range. If not in range, print out error message using error (‘error message’) statement. Use fprintf for output.

Explanation / Answer

if (R<=-10 || R>=10)

else

if (R>=0)

sq = sqrt(R);

fprintf('The square root of %.3f is %.3f ',R,sq);

else

sq = sqrt((-1*R));

fprintf('%.3f is negative. The square root of %.3f is %.3f i ',R,R,sq);

end

end
