Finding maximum and minimum values in arrays
Let’s write a function file range.m that calculates the difference between the maximum and minimum value in a vector. The file should return a reply. Open an edit window. Create a function file like...

Localize minima and maxima of functions Let us try to find the local minima and maxima for the function func(x). The interval of interest is [-6 0]. The algorithms are iterative. There are 2...
bsxfun
bsxfun – Apply element-by-element binary operation to two arrays with singleton expansion enabled Syntax C = bsxfun(fun,A,B) Description C = bsxfun(fun,A,B) applies an element-by-element binary operation to arrays A and B, with singleton expansion...
arrayfun
arrayfun – Apply function to each element of array Syntax A = arrayfun(fun, S) A = arrayfun(fun, S, T, …) [A, B, …] = arrayfun(fun, S, …) [A, …] = arrayfun(fun, S, …, ‘param1’,...
accumarray
Construct array with accumulation Syntax A = accumarray(subs,val) A = accumarray(subs,val,sz) A = accumarray(subs,val,sz,fun) A = accumarray(subs,val,sz,fun,fillval) A = accumarray(subs,val,sz,fun,fillval,issparse) A = accumarray({subs1, subs2, …}, val, …) Description accumarray groups elements from a data...
Matlab Expressions
Matlab Expressions Variables Like most other programming languages, the MATLAB language provides mathematical expressions, but unlike most programming languages, these expressions involve entire matrices. MATLAB does not require any type declarations or dimension statements....
Examples of Expressions
You have already seen several examples of MATLAB expressions. Here are a few more examples, and the resulting values. rho = (1+sqrt(5))/2 rho = 1.6180 a = abs(3+4i) a = 5 z = sqrt(besselk(4/3,rho-i))...
