This means you will need to include a period before the multiplication sign whenever doing element-by-element multiplication of vectors. If you are looking to multiply each element individually, the proper MATLAB syntax is to use the dot operator. Multiplication of a vector to another vector gets a little more complicated. See the following example where a vector Diameter is calculated by multiplying Radius by 2. When you are looking to multiply the same scalar value to all values in a vector, format as you would for multiplying two scalar values. NOTE: When doing Vector to Vector Addition/Subtraction in MATLAB, the dimensions must ALWAYS be identical. In the following example, the vector Diff is generated by subtracting Short from Tall. Addition or subtraction will be completed on an element-by-element basis. In the following example, Kelvin is created by adding 273.15 to all elements of Celsius.Īdding/subtracting vectors in MATLAB is formatted the same as that with scalars. Add (or subtract) the scalar value to the vector directly. There may be a time when you simply need to add (or subtract) the same value to all values in a vector. This page overviews some standard vector mathematic operations in MATLAB. When variables are in vector form, handling them is similar to that of a standard scalar variable. (March 13, 1998).Often, you will need to conduct standard mathematic operations in MATLAB.
