You can adjust it until you get what you want. your 't' and 'm' must be the same size; open the variable 't' from Workspace and look what index contains the value of ~600. 5 to 1. I want to enter a number and see the result. I would like to plot this range of values VS theata_i or theata_t but can not since only one value is being assigned to the variable "reflectedPerpendic" Find the treasures in MATLAB Central and discover how the community can help you! Start Hunting! I would like to keep the negative values that are equal or less than -0. When you apply the exponential to this smaller range, the x co-ordinates will then spread out in a gradual way where higher values of x will certainly make the value go farther along the x-axis, but not too far away like you saw in your original plot. Hello to everyone. Is there anything i can do to extract directly the values ranging from 300 Khz to I have this function where f has values (18 19 20 21 22), and I should compute the value of the function for each value of f and plot each value. Learn more about range, integer . mat file. I have an . How do I know the full range of values? Especially that I expected to have up to 255, that is `[0,255], and if we analyze the range of the bins below we will have the following for the ten bins respectively: 0-16. Locate position in sorted vector, fast. Examples. 4. By If X is a vector, then range(X) is the range of the values in X. Follow 3 views (last 30 days) Show older comments. I have two columns within a table of 1537090 x 2. I want to restrict the output of the arc cosine to be in the range [-1,1], but I want to know if there is built-in Matlab function for this task and if it is possible for example merge @max & @min simultaneoulsy in the function bsxfun to achieve this task. ) %it is just a example i want to know if there are multiple number of say x with other constant say a and b. ) Dear All, I wrote this code to find the max value of function y within the (-0. Each value in the array used for the 'Tick' property is a separate tick. If it exceeds the upper value it sets to the upper value and same for lower value. 7 ; ymax = 12. for example i want to select all the elements that are lower than 182 and swap/change them. The XDisplayData property controls the order in which the values appear along the x-axis in the chart. Find the treasures in MATLAB Central and discover how the community can help you! Start Hunting! In this MATLAB program, first of all we call “linspace” function to create a vector “x”, having linearly spaced values from 0 to 50. Commented Nov Learn more about solve, plot, vectors, plotting MATLAB I have a very simple expression with 2 variables , R1 and R2, that depend on each other. Instead of passing in arrays, you'll want to take the I have 5 values for x (x = 0, 15, 30, 55, and 85) and an equation with cos, say cos(x), and I need to find the answer for each of these values. I have both an x and f(x). 5 and should be increasing by one. How do I do this? Skip to main content. 5 115. Since the outer bins are then much wider (because they actually extend to Inf on the x axis), which you can correct by setting the axis xlim. For example if my x-axis is days of the month, my bars would represent the range between the max and min temperatures for that day. Ask Question Asked 13 years, 10 months ago. I have a range of very small numbers to plot in a graph but MATLAB isn't accepting what I want. I have to define two vectors that include the following values: Cis = all the values between -90 and 90 Tran However, I do not see a range of values for the reflectedPerpendic variable. Then each of the initial x points has a corresponding f(x). xlsx containing an array of X_values versus 6 columns of Y_ values. 5-99 99-115. 03) and keep the positive values that are equal or greater than 0. Ask Question Asked 11 years, 7 months ago. , -0. Sometimes it is useful to simultaneously change the values of several existing array elements. 7 ; ymin = -0. MATLAB Answers. y = range(X,dim) returns the range along the operating dimension dim of X. Link. Given a number, quickly check which interval it is in? 0. How to Change X and Y Axis (Axes) Limits in MATLAB. I need to plot the max value in y between the x range I have mentioned. Thus, you want to use a part of 'time' array from index 1 to 20. 9195 %Use the index of the maximum f(x) value to find the x value which produced function [b,c]=findInSorted(x,range) %findInSorted fast binary search replacement for ismember(A,B) for the %special case where the first input argument is sorted. As linear algebra would've told you: the determinant of a matrix is a single number. The lower half of the colormap corresponds to values that are outside the range of C, so those I want to get some specific values from a Matlab Figure. If X is a vector, then range(X) is the range of the values in X. Show -2 older comments Hide -2 older comments. Thanks in advance. If xvar and yvar both specify multiple variables, the number of variables must be the same. Change x-Axis to Logarithmic Scale Replace Values That Meet Condition. Implement the function in matlab so that it takes two arguments: x, and h (make sure to vectorize it with masks). Hi there, I am very new to Matlab and haven't been able to find the following solution. How do I create a regularly-spaced array of values in MATLAB?
