Input a Vector as Function Argument

Hi,

I was facing this problem in inputing a vector to my user defined function. I have defined a function that needs two inputs to perform some operations. However, when it try to pass on a vector containing two element to the function it shows need more arguments error.

x = [2 , 4]
y = sq(x)

function out = sq(a , b)
    out = a.^2 + b;
end

Can somebody show me how to do it right?

I will be very grateful.

Thanks a lot!

Either

x = [2 , 4]
y = sq(x(1),x(2))

function out = sq(a , b)
    out = a.^2 + b;
end

or

x = [2 , 4]
y = sq(x)

function out = sq(x)
a = x(1); b = x(2);
    out = a.^2 + b;
end

Use evalc

func = @(a, b) a+b

func = function_handle with value:
    @(a,b)a+b

InputArgumentsNumeric = [1, 2]

InputArgumentsNumeric = 1x2

1 2

<mw-icon class=""></mw-icon>

<mw-icon class=""></mw-icon>

InputArgumentsString = strjoin(cellstr(num2str(InputArgumentsNumeric')),',')

InputArgumentsString = '1,2'

[~,output] = evalc("func(" + InputArgumentsString + ")")

output = 3
