Web20 apr. 2011 · This means that if f returns a scalar, x will be a scalar and if it returns a vector x will be a vector. In your example, this holds as long as t is also a scalar - otherwise the result will depend on how t* [output of f] is evaluated. Example function o1 = f (N) o1 = zeros (1,N); end Here f returns a scalar if N=1 and a vector for N>1.

Matlab - how to make this work for both scalars and vectors

WebScalar operations produce a new matrix with same number of rows and columns with each element of the original matrix added to, subtracted from, multiplied by or divided by the number. Example Create a script file with the following code − Live Demo a = [ 10 12 23 ; 14 8 6; 27 8 9]; b = 2; c = a + b d = a - b e = a * b f = a / b Web22 mar. 2013 · 1 Answer Sorted by: 16 You just use the * operator, as you might expect, e.g. y = x * k; where x is the input image, k is a scalar value, and y is the resulting scaled image.
