Incorrect dimensions for raising a matrix to a power

How can I solve this problem

x=0:0.01:4

y=1/(sqrt((1-x.^2)^2+(4*0.01^2*x.^2)))

Error using ^ (line 51)

Incorrect dimensions for raising a matrix to a power. Check that the matrix is square and the power is

a scalar. To perform elementwise matrix powers, use '.^'.

x=0:0.01:4

x = 1×401

0 0.0100 0.0200 0.0300 0.0400 0.0500 0.0600 0.0700 0.0800 0.0900 0.1000 0.1100 0.1200 0.1300 0.1400 0.1500 0.1600 0.1700 0.1800 0.1900 0.2000 0.2100 0.2200 0.2300 0.2400 0.2500 0.2600 0.2700 0.2800 0.2900

y=1./(sqrt((1-x.^2).^2+(4*0.01^2*x.^2)))

y = 1×401

1.0000 1.0001 1.0004 1.0009 1.0016 1.0025 1.0036 1.0049 1.0064 1.0082 1.0101 1.0122 1.0146 1.0172 1.0200 1.0230 1.0263 1.0298 1.0335 1.0374 1.0417 1.0461 1.0509 1.0558 1.0611 1.0667 1.0725 1.0786 1.0850 1.0918
