What does the following command return (i.e. b)? a=4+0.2 randn (1,100);b= round(a) a column vector of 100 uniformly distributed random numbers between 0.2 and 4 a column vector of 100 random integers with Gaussian distribution with the mean 4 and standard deviation 0.2 a row vector of 100 random integers with Gaussian distribution with the mean 4 and standard deviation 0.2 a row vector of 100 uniformly distributed random integers between 0.2 and 4 Which of the following choices is the appropriate syntax to calculate log5(14) ? (hint: logb(x)= logp(b)logp(x) where p is an arbitrary base for the logarithm? log10(14)/log(5) ln(14)/ln(5) log10(14)/log10(5) log5(14) Which of the commands below returns a 44 matrix containing uniform random numbers between 2 and 5? 2+5rand(4,4)5+3rand(4)2+3randn(4,4)2+3rand(4) Which of the functions below returns the angle whose sine is 0.3. Is this angle in degrees or radians? sin(0.3); radians asin(0.3); degrees asin(0.3); radians asin(0.3* pi/180); degrees Which of the following choices is the appropriate syntax to calculate log3(20)( hint: logb(x)=logp(b)logp(x) where p is an arbitrary base for the logarithm). log10(20)/log(3) ln(20)/ln(3) log2(20)/log2(3) log3(20)
