Question

Subject: Matlab

Which of the following expressions generates an evenly spaced
vector, which contains 50 values between 10 and 50.
a. x=linspace(10,10:50)
b. x=linspace(10,10,50)
c. x=linspace(10,50,10)

Answer 1

The correct expression to generate an evenly spaced vector of 50 values between 10 and 50 in MATLAB is x = linspace(10, 50, 50).

Step-by-step explanation:

The student asked which expression would generate an evenly spaced vector containing 50 values between 10 and 50 in MATLAB. The correct answer is the expression that uses the linspace function with the appropriate parameters for the start value, end value, and the number of points.

The correct expression is:

x = linspace(10, 50, 50);

This function call to linspace starts at 10, ends at 50, and generates 50 evenly spaced points. Option a is incorrect because the second argument should not be a vector. Option b is incorrect as it specifies the start and end points to be the same, which would result in a vector of repeating 10s. Option c only generates 10 points, not the 50 that are required.
